Question: Who is the earliest known female mathematician?

Hypatia





Hypatia[lower-alpha 1] (born c. 350–370; died 415 AD)[1][5] was a Hellenistic Neoplatonist philosopher, astronomer, and mathematician, who lived in Alexandria, Egypt, then part of the Eastern Roman Empire. She was a prominent thinker of the Neoplatonic school in Alexandria, where she taught philosophy and astronomy.[6] She is the first female mathematician whose life is reasonably well recorded.[7] Hypatia was renowned in her own lifetime as a great teacher and a wise counselor. She is known to have written a commentary on Diophantus's thirteen-volume Arithmetica, which may survive in part, having been interpolated into Diophantus's original text, and another commentary on Apollonius of Perga's treatise on conic sections, which has not survived. Many modern scholars also believe that Hypatia may have edited the surviving text of Ptolemy's Almagest, based on the title of her father Theon's commentary on Book III of the Almagest.
Hypatia is known to have constructed astrolabes and hydrometers, but did not invent either of these, which were both in use long before she was born. Although she herself was a pagan, she was tolerant towards Christians and taught many Christian students, including Synesius, the future bishop of Ptolemais. Ancient sources record that Hypatia was widely beloved by pagans and Christians alike and that she established great influence with the political elite in Alexandria. Towards the end of her life, Hypatia advised Orestes, the Roman prefect of Alexandria, who was in the midst of a political feud with Cyril, the bishop of Alexandria. Rumors spread accusing her of preventing Orestes from reconciling with Cyril and, in March 415 AD, she was murdered by a mob of Christians led by a lector named Peter.[8][9]
Hypatia's death shocked the empire and transformed her into a "martyr for philosophy", leading future Neoplatonists such as Damascius to become increasingly fervent in their opposition to Christianity. During the Middle Ages, Hypatia was co-opted as a symbol of Christian virtue and scholars believe she was part of the basis for the legend of Saint Catherine of Alexandria. During the Age of Enlightenment, she became a symbol of opposition to Catholicism. In the nineteenth century, European literature, especially Charles Kingsley's 1853 novel Hypatia, romanticized her as "the last of the Hellenes". In the twentieth century, Hypatia became seen as an icon for women's rights and a precursor to the feminist movement. Since the late twentieth century, some portrayals have associated Hypatia's death with the destruction of the Library of Alexandria, despite the historical fact that the library no longer existed during Hypatia's lifetime.[10]
Life
Upbringing

Hypatia was the daughter of the mathematician Theon of Alexandria (c. 335 – c. 405 AD).[14][15][16] According to classical historian Edward J. Watts, Theon was the head of a school called the "Mouseion", which was named in emulation of the Hellenistic Mouseion,[15] whose membership had ceased in the 260s AD.[17] Theon's school was exclusive, highly prestigious, and doctrinally conservative.[18] Theon rejected the teachings of Iamblichus[18] and may have taken pride in teaching a pure, Plotinian Neoplatonism.[18] Although he was widely seen as a great mathematician at the time,[11][13][19] Theon's mathematical work has been deemed by modern standards as essentially "minor",[11] "trivial",[13] and "completely unoriginal".[19] His primary achievement was the production of a new edition of Euclid's Elements, in which he corrected scribal errors that had been made over the course of nearly 700 years of copying.[11][12][13] Theon's edition of Euclid's Elements became the most widely-used edition of the textbook for centuries[12][20] and almost totally supplanted all other editions.[20]
Nothing is known about Hypatia's mother, who is never mentioned in any of the extant sources.[21][22][23] Theon dedicates his commentary on Book IV of Ptolemy's Almagest to an individual named Epiphanius, addressing him as "my dear son",[24][25] indicating that he may have been Hypatia's brother,[24] but the Greek word Theon uses (teknon) does not always mean "son" in the biological sense and was often used merely to signal strong feelings of paternal connection.[24][25] Hypatia's exact year of birth is still under debate, with suggested dates ranging from 350 to 370 AD.[26][27][28] Many scholars have followed Richard Hoche in inferring that Hypatia was born around 370.[29][30] According to a description of Hypatia from the lost work Life of Isidore by the Neoplatonist historian Damascius (c. 458 – c. 538), preserved in the entry for her in the Suda, a tenth-century Byzantine encyclopedia, Hypatia flourished during the reign of Arcadius.[29][30] Hoche reasoned that Damascius's description of her physical beauty would imply that she was at most 30 at that time, and the year 370 was 30 years prior to the midpoint of Arcadius's reign.[29][30] In contrast, theories that she was born as early as 350 are based on the wording of the chronicler John Malalas (c. 491 – 578), who calls her old at the time of her death in 415.[31][28] Robert Penella argues that both theories are weakly based, and that her birth date should be left unspecified.[29]
Career
Hypatia was a Neoplatonist,[18] but, like her father, she rejected the teachings of Iamblichus and instead embraced the original Neoplatonism formulated by Plotinus.[18] The Alexandrian school was renowned at the time for its philosophy[26] and Alexandria was regarded as second only to Athens as the philosophical capital of the Greco-Roman world.[26] Hypatia taught students from all over the Mediterranean.[32] According to Damascius, she lectured on the writings of Plato and Aristotle.[33][34][35][36] He also states that she walked through Alexandria in a tribon, a kind of cloak associated with philosophers, giving impromptu public lectures.[37][38][39]

According to Watts, two main varieties of Neoplatonism were taught in Alexandria during the late fourth century.[40] The first was the overtly pagan religious Neoplatonism taught at the Serapeum, which was greatly influenced by the teachings of Iamblichus.[40] The second variety was the more moderate and less polemical variety championed by Hypatia and her father Theon,[41] which was based on the teachings of Plotinus.[41] Although Hypatia herself was a pagan, she was tolerant of Christians.[42][43] In fact, every one of her known students was Christian.[44] One of her most prominent pupils was Synesius of Cyrene,[45][26][46][47] who went on to become a bishop of Ptolemais (now in eastern Libya) in 410.[48][47] Afterward, he continued to exchange letters with Hypatia[49][46][47] and his extant letters are the main sources of information about her career.[46][50][51][47][52] Seven letters by Synesius to Hypatia have survived,[47][46] but none from her addressed to him are extant.[47] In a letter written in around 395 to his friend Herculianus, Synesius describes Hypatia as "... a person so renowned, her reputation seemed literally incredible. We have seen and heard for ourselves she who honorably presides over the mysteries of philosophy."[46]
The Christian historian Socrates of Constantinople, a contemporary of Hypatia, describes her in his Ecclesiastical History:[21]
There was a woman at Alexandria named Hypatia, daughter of the philosopher Theon, who made such attainments in literature and science, as to far surpass all the philosophers of her own time. Having succeeded to the school of Plato and Plotinus, she explained the principles of philosophy to her auditors, many of whom came from a distance to receive her instructions. On account of the self-possession and ease of manner which she had acquired in consequence of the cultivation of her mind, she not infrequently appeared in public in the presence of the magistrates. Neither did she feel abashed in going to an assembly of men. For all men on account of her extraordinary dignity and virtue admired her the more.[33]

Philostorgius, another Christian historian, who was also a contemporary of Hypatia, states that she excelled her father in mathematics[46] and the lexicographer Hesychius of Alexandria records that, like her father, she was also an extraordinarily talented astronomer.[46][53] Damascius writes that Hypatia was "exceedingly beautiful and fair of form",[54][55] but nothing else is known regarding her physical appearance[56] and no ancient depictions of her have survived.[57] Damascius states that Hypatia remained a lifelong virgin[58][59] and that, when one of the men who came to her lectures tried to court her, she tried to sooth his lust by playing the lyre.[60][55][lower-alpha 2] When he refused to abandon his pursuit, she rejected him outright,[62][60][55] displaying her bloody menstrual rags and declaring "This is what you really love, my young man, but you do not love beauty for its own sake."[62][60][55][34] Damascius further relates that the young man was so traumatized that he abandoned his desires for her immediately.[62][60][55]
Michael A. B. Deakin, a historian of mathematics, argues that Hypatia's menstruation was proof of her celibacy,[63][64] since, in ancient times, menarche generally occurred around the time a woman reached marriageable age, much later than in developed countries today,[63][64] and, since no reliable methods of birth control existed,[63][64] menstruation would have actually been a relatively rare occurrence for any woman who was not devoted to a life of celibacy.[63][64] Charlotte Booth, a British Egyptologist, rejects this assertion as unfounded,[65] stating that Pharaonic texts make reference to amenorrhea, the unusual absence of menstruation in a woman of the proper age,[64] and that Egyptian homes from the Hellenistic Period onwards had rooms under the stairs called "women's spaces" that were specially designated for women to stay while they were menstruating.[64] Both of these would be inexplicable if menstruation was indeed "rare".[65] Booth therefore regards Hypatia's menstruation, not as evidence of her celibacy, but rather of her "femininity and even fertility."[66]
Death
Background

From 382 – 412, the bishop of Alexandria was Theophilus.[68] Theophilus was militantly opposed to Iamblichean Neoplatonism[68] and, in 391, he demolished the Serapeum.[69][70] Despite this, Theophilus tolerated Hypatia's school and seems to have regarded Hypatia as his ally.[21][71][68] Theophilus supported the bishopric of Hypatia's pupil Synesius,[72][21] who describes Theophilus in his letters with love and admiration.[73][71] Theophilus also permitted Hypatia herself to establish close relationships with the Roman prefects and other prominent political leaders.[68] Partly as a result of Theophilus's tolerance, Hypatia became extremely popular with the people of Alexandria[74] and exerted profound political influence.[74]
Theophilus died unexpectedly in 412.[68] He had been training his nephew Cyril,[75] but had not officially named him as his successor.[75] A violent power struggle over the diocese broke out between Cyril and his rival Timothy.[76] Cyril won and immediately began to punish those who had supported Timothy;[76] he closed the churches of the Novatianists, who had supported Timothy, and confiscated their property.[76] Hypatia's school seems to have immediately taken a strong distrust towards the new bishop,[73][71] as evidenced by the fact that, in all his vast correspondences, Synesius only ever wrote one letter to Cyril, in which he treats the younger bishop as inexperienced and misguided.[73] In a letter written to Hypatia in 413, Synesius requests her to intercede on behalf of two individuals impacted by the ongoing civil strife in Alexandria,[77][78][79] insisting, "You always have power, and you can bring about good by using that power."[77] He also reminds her that she had taught him that a Neoplatonic philosopher must introduce the highest moral standards to political life and act for the benefit of their fellow citizens.[77]
In 414, Cyril closed all the synagogues in Alexandria, confiscated all the property belonging to the Jews, and expelled all the Jews from the city.[76] Orestes, the Roman prefect of Alexandria, who was also a close friend of Hypatia[21] and a recent convert to Christianity,[80][21][81] was outraged by Cyril's actions and sent a scathing report to the emperor.[76][82][21] The conflict escalated and a riot broke out in which the parabalani, a group of Christian clerics under Cyril's authority, nearly killed Orestes.[76] As punishment, Orestes had Ammonius, the monk who had started the riot, publicly tortured to death.[76][83][84] Cyril tried to proclaim Ammonius a martyr,[76][83][85] but Christians in Alexandria were disgusted,[83][86] since Ammonius had been killed for inciting a riot and attempting to murder the governor, not for his faith.[83] Prominent Alexandrian Christians intervened and forced Cyril to drop the matter.[76][83][86] Nonetheless, Cyril's feud with Orestes continued.[87] Orestes frequently consulted Hypatia for advice[88][89] because she was well-liked among both pagans and Christians alike,[90] she had not been involved in any previous stages of the conflict,[90] and she had an impeccable reputation as a wise counselor.[90]
Despite Hypatia's popularity, Cyril and his allies attempted to discredit her and undermine her reputation.[91][92] Socrates Scholasticus mentions rumors accusing Hypatia of preventing Orestes from reconciling with Cyril.[89][92] Traces of other rumors that spread among the Christian populace of Alexandria may be found in the writings of the seventh-century Egyptian Coptic bishop John of Nikiû,[40][92] who alleges in his Chronicle that Hypatia had engaged in satanic practices and had intentionally hampered the church's influence over Orestes:[93][94][95][92]
And in those days there appeared in Alexandria a female philosopher, a pagan named Hypatia, and she was devoted at all times to magic, astrolabes and instruments of music, and she beguiled many people through her Satanic wiles. And the governor of the city honoured her exceedingly; for she had beguiled him through her magic. And he ceased attending church as had been his custom... And he not only did this, but he drew many believers to her, and he himself received the unbelievers at his house.[93]

Murder

According to Socrates Scholasticus, during the Christian season of Lent in March 415, a mob of Christians under the leadership of a lector named Peter, raided Hypatia's carriage as she was travelling home.[98][99][100] They dragged her into a building known as the Kaisarion, a former pagan temple and center of the Roman imperial cult in Alexandria that had been converted into a Christian church.[100][98][90][100] There, the mob stripped Hypatia naked and murdered her using ostraka,[98][101][102][103] which can either be translated as "roof tiles" or "oyster shells".[98] Damascius adds that they also cut out her eyeballs.[104] They tore her body into pieces[98][104][103] and dragged her mangled limbs through the town to a place called Cinarion, where they set them on fire.[98][104][103] According to Watts, this was in line with the traditional manner in which Alexandrians carried the bodies of the "vilest criminals" outside the city limits to cremate them as a way of symbolically purifying the city.[104][105] Although Socrates Scholasticus never explicitly identifies Hypatia's murderers, they are commonly assumed to have been members of the parabalani.[106] Christopher Haas disputes this identification, arguing that the murderers were more likely "a crowd of Alexandrian laymen".[107]
Socrates Scholasticus presents Hypatia's murder as entirely politically motivated[108] and makes no mention of any role that Hypatia's paganism might have played in her death.[108] Instead, he reasons that "she fell a victim to the political jealousy which at that time prevailed. For as she had frequent interviews with Orestes, it was calumniously reported among the Christian populace that it was she who prevented Orestes from being reconciled to the bishop."[98][109] Socrates Scholasticus unequivocally condemns the actions of the mob, declaring, "Surely nothing can be farther from the spirit of Christianity than the allowance of massacres, fights, and transactions of that sort."[98][110][105]
The Canadian mathematician Ari Belenkiy has argued that Hypatia may have been involved in a controversy over the date of the Christian holiday of Easter 417 and that she was killed on the vernal equinox while making astronomical observations.[111] Classical scholars Alan Cameron and Edward J. Watts both dismiss this hypothesis, noting that there is absolutely no evidence in any ancient text to support any part of the hypothesis.[112][113]
Aftermath
Hypatia's death sent shockwaves throughout the empire;[114][40] for centuries, philosophers had been seen as effectively untouchable during the displays of public violence that sometimes occurred in Roman cities[114] and the murder of a female philosopher at the hand of a mob was seen as "profoundly dangerous and destabilizing".[114] Although no concrete evidence was ever discovered definitively linking Cyril to the murder of Hypatia,[40] it was widely believed that he had ordered it.[89][40] Even if Cyril had not directly ordered the murder himself, it was self-evident that his smear campaign against Hypatia had inspired it.[40] The Alexandrian council was alarmed at Cyril's conduct[40] and sent an embassy to Constantinople.[40] Theodosius II's advisors launched an investigation to determine Cyril's role in the murder.[110]
The investigation resulted in the emperors Honorius and Theodosius II issuing an edict in autumn of 416, which attempted to remove the parabalani from Cyril's power and instead place them under the authority of Orestes.[110][40][115][116] The edict restricted the parabalani from attending "any public spectacle whatever" or entering "the meeting place of a municipal council or a courtroom."[117] It also severely restricted their recruitment by limiting the total number of parabalani to no more than five hundred.[116] Cyril himself allegedly only managed to escape even more serious punishment by bribing one of Theodosius II's officials.[110] Watts argues that Hypatia's murder was the turning point in Cyril's fight to gain political control of Alexandria.[118] Hypatia had been the lynchpin holding Orestes's opposition against Cyril together[40] and, without her, the opposition quickly collapsed.[40] Two years later, Cyril overturned the law placing the parabalani under Orestes's control[118] and, by the early 420s, Cyril had come to dominate the Alexandrian council.[118]
Works
Hypatia has been described as a universal genius,[119] but she was probably more of a teacher and commentator than an innovator.[120][121][21][122] No evidence has been found that Hypatia ever published any independent works on philosophy[123] and she does not appear to have made any groundbreaking mathematical discoveries.[120][121][21][122] During Hypatia's time period, scholars preserved classical mathematical works and commented on them to develop their arguments, rather than publishing original works.[120][124][125] It has also been suggested that the closure of the Mouseion and the destruction of the Serapeum may have led Hypatia and her father to focus their efforts on preserving seminal mathematical books and making them accessible to their students.[123] The Suda mistakenly states that all of Hypatia's writings have been lost,[126] but modern scholarship has identified several works by her as extant.[126] This kind of authorial uncertainty is typical of female philosophers from antiquity.[127] Hypatia wrote in Greek, which was the language spoken by most educated people in the Eastern Mediterranean at the time.[26] In classical antiquity, astronomy was seen as being essentially mathematical in character.[128] Furthermore, no distinction was made between mathematics and numerology or astronomy and astrology.[128]
Edition of the Almagest

Hypatia is now known to have edited the existing text of Book III of Ptolemy's Almagest.[129][130][131] It was once thought that Hypatia had merely revised Theon's commentary on the Almagest,[133] based on the title of Theon's commentary on the third book of Almagest, which reads "Commentary by Theon of Alexandria on Book III of Ptolemy's Almagest, edition revised by my daughter Hypatia, the philosopher",[133][134] but, based on analysis of the titles of Theon's other commentaries and similar titles from the time period, scholars have concluded that Hypatia corrected, not her father's commentary, but the text of Almagest itself.[133][135] Her contribution is thought to be an improved method for the long division algorithms needed for astronomical computation.[132] The Ptolemaic model of the universe was geocentric, meaning it taught that the sun revolved around the earth.[132] In the Almagest, Ptolemy proposed a division problem for calculating the number of degrees swept out by the sun in a single day as it orbits the earth.[132] In his early commentary, Theon had tried to improve upon Ptolemy's division calculation.[132] In the text edited by Hypatia, a tabular method is detailed.[132] This tabular method might be the "astronomical table" which historic sources attribute to Hypatia.[132] Classicist Alan Cameron additionally states that it is possible Hypatia may have edited, not only Book III, but all nine extant books of the Almagest.[130]
Independent writings

Hypatia wrote a commentary on Diophantus's thirteen-volume Arithmetica, which had been written sometime around the year 250 AD.[34][138][19][139] It set out more than 100 mathematical problems, for which solutions are proposed using algebra.[140] For centuries, scholars believed that this commentary had been lost.[126] Only volumes one through six of the Arithmetica have survived in the original Greek,[141][19][137] but at least four additional volumes have been preserved in an Arabic translation produced around the year 860.[19][139] The Arabic text contains numerous expansions not found in the Greek text,[19][139] including verifications of Diophantus's examples and additional problems.[19]
Cameron states that the most likely source of the additional material is Hypatia herself,[19] since Hypatia is the only ancient writer known to have written a commentary on the Arithmetica[19] and the additions appear to follow the same methods used by her father Theon.[19] The first person to deduce that the additional material in the Arabic manuscripts came from Hypatia was the nineteenth-century scholar Paul Tannery.[136][142] In 1885, Sir Thomas Heath published the first English translation of the surviving portion of the Arithmetica.[141] Heath argued that surviving text of Arithmetica is actually a school edition produced by Hypatia to aid her students.[141] According to Mary Ellen Waithe, Hypatia used an unusual algorithm for division (in the then-standard sexagesimal numeral system), making it easy for scholars to pick out which parts of the text she had written.[136]
The consensus that Hypatia's commentary is the source of the additional material in the Arabic manuscripts of the Arithmetica has been challenged by Wilbur Knorr, a historian of mathematics,[19] who argues that the interpolations are "of such low level as not to require any real mathematical insight" and that the author of the interpolations can only have been "an essentially trivial mind... in direct conflict with ancient testimonies of Hypatia's high caliber as a philosopher and mathematician."[19] Cameron rejects this argument, noting that "Theon too enjoyed a high reputation, yet his surviving work has been judged 'completely unoriginal.'"[19] Cameron also insists that "Hypatia's work on Diophantus was what we today might call a school edition, designed for the use of students rather than professional mathematicians."[19]
Hypatia also wrote a commentary on Apollonius of Perga's work on conic sections,[34][136][137] but this commentary is no longer extant.[136][137] She also created an "Astronomical Canon";[34] this is believed to have been either a new edition of the Handy Tables by the Alexandrian Ptolemy or the aforementioned commentary on his Almagest.[143][144][145] Based on a close reading in comparison with her supposed contributions to the work of Diophantus, Knorr suggests that Hypatia may also have edited Archimedes' Measurement of a Circle, an anonymous text on isometric figures, and a text later used by John of Tynemouth in his work on Archimedes' measurement of the sphere.[146] A high degree of mathematical accomplishment would have been needed to comment on Apollonius's advanced mathematics or the astronomical Canon.[120] Because of this, most scholars today recognize that Hypatia must have been among the leading mathematicians of her day.[120]
Reputed inventions

One of Synesius's letters describes Hypatia as having taught him how to construct a silver plane astrolabe as a gift for an official.[147][52][148][149] An astrolabe is a device used to calculate date and time based on the positions of the stars and planets.[147][150][151] It can also be used to predict where the stars and planets will be on any given date.[147][150][151] A "little astrolabe", or "plane astrolabe", is a kind of astrolabe that used stereographic projection of the celestial sphere to represent the heavens on a plane surface, as opposed to an armillary sphere, which was globe-shaped.[132][150] Armillary spheres were large and normally used for display;[150] whereas a plane astrolabe was portable and could be used for practical measurements.[150]
The statement from Synesius's letter has sometimes been wrongly interpreted to mean that Hypatia invented the plane astrolabe herself,[37][152] but the plane astrolabe is known to have been in use at least 500 years before Hypatia was born.[152][147][52][153] Hypatia may have learned how to construct a plane astrolabe from her father Theon,[132][148][150] who had written two treatises on astrolabes: one entitled Memoirs on the Little Astrolabe and another study on the armillary sphere in Ptolemy's Almagest.[150] Theon's treatise is now lost, but it was well-known to the Syrian bishop Severus Sebokht (575–667), who describes its contents in his own treatise on astrolabes.[150][154] Hypatia and Theon may have also studied Ptolemy's Planisphaerium, which describes the calculations necessary in order to construct an astrolabe.[155] Synesius's wording indicates that Hypatia did not design or construct the astrolabe herself, but merely acted as a guide and mentor during the process of constructing it.[13]
In another letter, Synesius requests Hypatia to construct him a "hydroscope", a device now known as a hydrometer, to determine the density or specific gravity of liquids.[152][156][148][157] Based on this request, it has been claimed that Hypatia invented the hydrometer herself.[152][158] The minute detail in which Synesius describes the instrument, however, indicates that he assumes she has never heard of the device,[159][160] but trusts she will be able to replicate it based on a verbal description.[159] Although modern authors frequently credit Hypatia with having developed a variety of other inventions,[159] these other attributions may all be discounted as spurious.[159] Booth concludes, "The modern day reputation held by Hypatia as a philosopher, mathematician, astronomer, and mechanical inventor, is disproportionate to the amount of surviving evidence of her life's work. This reputation is either built on myth or hearsay as opposed to evidence. Either that or we are missing all of the evidence that would support it."[158]
Legacy
Antiquity
Hypatia was not the last pagan, nor was she the last Neoplatonist philosopher.[161][162] Neoplatonism and paganism both survived for centuries after her death.[161][162] Booth notes that a massive number of new academic lecture halls were built in Alexandria at Kom el Dikka shortly after Hypatia's death, indicating that philosophy was clearly still taught in Alexandrian schools.[163] In fact, Neoplatonism thrived throughout the eastern Mediterranean during the next 200 years, with philosophers such as Hierocles of Alexandria, John Philoponus, Simplicius of Cilicia, and Olympiodorus the Younger continuing to make astronomical observations, teach mathematics, and write lengthy commentaries on the works of Plato and Aristotle.[161][162] Booth points out that Hypatia was not even the last female Neoplatonist philosopher.[163] Notable female Neoplatonists who followed her include: Aedesia, Asclepigenia, and Theodora of Emesa, all of whom lived out similar careers.[163]
According to Watts, however, Hypatia had no appointed successor, no spouse, and no offspring[110][164] and her sudden death not only left her legacy unprotected, but also triggered a backlash against her entire ideology.[165] Hypatia, with her tolerance towards Christian students and her willingness to cooperate with Christian leaders, had hoped to establish a precedent that Neoplatonism and Christianity could coexist peacefully and cooperatively.[166] Instead, her death and the subsequent failure by the Christian government to impose justice on her killers destroyed that notion entirely[166] and led future Neoplatonists such as Damascius to consider Christian bishops as "dangerous, jealous figures who were also utterly unphilosophical."[166] Hypatia became seen as a "martyr for philosophy"[166] and her murder led philosophers to adopt attitudes that increasingly emphasized the pagan aspects of their beliefs system[167] and helped create a sense of identity for philosophers as pagan traditionalists set apart from the Christian masses.[168] Thus, while Hypatia's death did not bring an end to Neoplatonist philosophy as a whole, Watts argues that it did bring an end to her particular variety of it.[169]
Shortly after Hypatia's murder, a forged anti-Christian letter appeared under her name.[170] Damascius was "anxious to exploit the scandal of Hypatia's death", and attributed responsibility for her murder to Bishop Cyril and his Christian followers.[171][172] A passage from Damascius's Life of Isidore, preserved in the Suda, concludes that Hypatia's murder was due to Cyril's envy over "her wisdom exceeding all bounds and especially in the things concerning astronomy".[173][174] Damascius's account of the Christian murder of Hypatia is the sole historical source attributing direct responsibility to Bishop Cyril.[174] At the same time, Damascius was not entirely kind to Hypatia either;[175][176] he characterizes her as nothing more than a wandering Cynic,[175][176] and compares her unfavorably with his own teacher Isidore of Alexandria,[175][176][177] remarking that "Isidorus greatly outshone Hypatia, not just as a man does over a woman, but in the way a genuine philosopher will over a mere geometer."[178]
Middle Ages

Hypatia's death was similar to those of Christian martyrs in Alexandria, who had been dragged through the streets during the Decian persecution in 250.[182][183][184] Other aspects of Hypatia's life also fit the mold for a Christian martyr, especially her lifelong virginity.[179][185] In the Early Middle Ages, Christians conflated Hypatia's death with stories of the Decian martyrs[179][185] and she became part of the basis for the legend of Saint Catherine of Alexandria, a virgin martyr said to have been exceedingly wise and well-educated.[179][180][181] The earliest attestation for the cult of Saint Catherine comes from the eighth century, around three hundred years after Hypatia's death.[186] One story tells of Saint Catherine being confronted by fifty pagan philosophers seeking to convert her,[187][181] but instead converting all of them to Christianity through her eloquence.[179][181] Another legend claimed that Saint Catherine had been a student of Athanasius of Alexandria.[183]
The Byzantine Suda encyclopedia contains a very long entry about Hypatia, which summarizes two different accounts of her life.[188] The first eleven lines come from one source and the rest of the entry comes from Damascius's Life of Isidore.[189] Most of the first eleven lines of the entry probably come from Hesychius's Onomatolos,[189] but some part are of unknown origin, including a claim that she was "the wife of Isidore the Philosopher" (apparently Isidore of Alexandria).[34][189][66] Watts describes this as a very puzzling claim, not only because Isidore of Alexandria was not born until long after Hypatia's death, and no other philosopher of that name contemporary with Hypatia is known,[190][191][192] but also because it contradicts Damascius's own statement quoted in the same entry about Hypatia being a lifelong virgin.[190] Watts suggests that someone probably misunderstood the meaning of the word gynē used by Damascius to describe Hypatia in his Life of Isidore, since the same word can mean either "woman" or "wife".[193]
The Byzantine intellectual Photios (c. 810/820–893) includes both Damascius's account of Hypatia and Socrates Scholasticus's in his Bibliotheke.[193] In his own comments, Photios remarks on Hypatia's great fame as a scholar, but does not mention her death, perhaps indicating that he saw her scholarly work as more significant.[194] The intellectual Eudokia Makrembolitissa (1021–1096), the second wife of Byzantine emperor Constantine X Doukas, was described by the historian Nicephorus Gregoras as a "second Hypatia".[195]
Early modern period

The early eighteenth-century Deist scholar John Toland used the murder of Hypatia as the basis for the anti-Catholic tract, Hypatia: Or the History of a most beautiful, most vertuous, most learned, and every way accomplish'd Lady; who was torn to pieces by the Clergy of Alexandria, to gratify the pride, emulation, and cruelty of their Archbishop, commonly, but undeservedly, stiled St. Cyril.[198][196][197] In order to portray Hypatia's death in the worst possible light, Toland changed the story and invented elements not found in any of the ancient sources.[196][197] In 1721, Thomas Lewis wrote a response defending Cyril entitled The History of Hypatia, a most Impudent School-Mistress of Alexandria: Murder'd and torn to Pieces by the Populace, in Defence of Saint Cyril and the Alexandrian Clergy from the Aspersions of Mr. Toland.[196][199] Lewis rejected Damascius's account as unreliable out of hand on account of the fact that its author was "a heathen"[199] and then proceeded to argue that Socrates Scholasticus was "a Puritan", who was consistently biased against Cyril.[199]
Voltaire, in his Examen important de Milord Bolingbroke ou le tombeau de fantisme (1736) interpreted Hypatia as a believer in "the laws of rational Nature" and "the capacities of the human mind free of dogmas"[196][120] and described her death as "a bestial murder perpetrated by Cyril's tonsured hounds, with a fanatical gang at their heels".[196] Later, in an entry for his Dictionnaire philosophique (1772), Voltaire again portrayed Hypatia as a freethinking deistic genius brutally murdered by ignorant and misunderstanding Christians.[200][120][201] Most of the entry ignores Hypatia herself altogether[201] and instead deals with the controversy over whether or not Cyril was responsible for her death.[201] Voltaire concludes with the snide remark that "When one strips beautiful women naked, it is not to massacre them."[200][201]
In his monumental work The History of the Decline and Fall of the Roman Empire, the English historian Edward Gibbon expanded on Toland and Voltaire's misleading portrayals by declaring Cyril as the sole cause of all evil in Alexandria at the beginning of the fifth century[200] and construing Hypatia's murder as evidence to support his polemical thesis that the rise of Christianity was the sole cause of the Roman Empire's decline.[202] He remarks on Cyril's continued veneration as a Christian saint, commenting that "superstition [Christianity] perhaps would more gently expiate the blood of a virgin, than the banishment of a saint."[203] In response to these accusations, Catholic authors, as well as some French Protestants, insisted with increased vehemence that Cyril had absolutely no involvement in Hypatia's murder and that Peter the Lector was solely responsible.[201] In the course of these heated debates, Hypatia herself tended to be cast aside and ignored, while the debates focused far more intently on the question of whether Peter the Lector had acted alone or under Cyril's orders.[201]
Nineteenth century



In nineteenth century European literary authors spun the legend of Hypatia as part of neo-Hellenism, a movement that romanticised ancient Greeks and their values.[120] Interest in the "literary legend of Hypatia" began to rise.[200] Diodata Saluzzo Roero's 1827 Ipazia ovvero delle Filosofie suggested that Cyril had actually converted Hypatia to Christianity, and that she had been killed by a "treacherous" priest.[205]
In his 1852 Hypatie and 1857 Hypathie et Cyrille, French poet Charles Leconte de Lisle portrayed Hypatia as the epitome of "vulnerable truth and beauty".[206] Leconte de Lisle's first poem portrayed Hypatia as a woman born after her time, a victim of the laws of history.[203][207] His second poem reverted to the eighteenth-century Deistic portrayal of Hypatia as the victim of Christian brutality,[208][97] but with the twist that Hypatia tries and fails to convince Cyril that Neoplatonism and Christianity are actually fundamentally the same.[209][97] Charles Kingsley's 1853 novel Hypatia; Or, New Foes with an Old Face was originally intended as a historical treatise,[210][211] but instead became a typical mid-Victorian romance with a militantly anti-Catholic message,[210][211] portraying Hypatia as a "helpless, pretentious, and erotic heroine"[212] with the "spirit of Plato and the body of Aphrodite."[213]
Kingsley's novel was tremendously popular;[214][215] it was translated into several European languages[215][216] and remained continuously in print for the rest of the century.[216] It promoted the romantic vision of Hypatia as "the last of the Hellenes"[215] and was quickly adapted into a broad variety of stage productions,[216] the first of which was a play written by Elizabeth Bowers, performed in Philadelphia in 1859, starring the writer herself in the titular role.[216] On 2 January 1893, a much higher-profile stage play adaptation Hypatia, written by G. Stuart Ogilvie and produced by Herbert Beerbohm Tree,[217][218] opened at the Haymarket Theatre in London.[217][218] The title role was initially played by Julia Neilson, and it featured an elaborate musical score written by the composer Hubert Parry.[217][218] The novel also spawned works of visual art,[204] including an 1867 portrait of Hypatia as a young woman by the early photographer Julia Margaret Cameron[204][219] and an 1885 painting by Charles William Mitchell showing a nude Hypatia standing before an altar in a church.[204]
At the same time, European philosophers and scientists described Hypatia as the last representative of science and free inquiry before a "long medieval decline".[120] In 1843, German authors Soldan and Heppe argued in their highly influential History of the Witchcraft Trials that Hypatia may have been, in effect, the first famous "witch" punished under Christian authority (see witch-hunt).[220]
Hypatia was honored as an astronomer when 238 Hypatia, a main belt asteroid discovered in 1884, was named for her. The lunar crater Hypatia was also named for her, in addition to craters named for her father Theon. The 180km Rimae Hypatia are located north of the crater, one degree south of the equator, along the Mare Tranquillitatis.[221]
Twentieth century

In 1908, the American writer Elbert Hubbard published a putative biography of Hypatia as part of his series Little Journeys to the Homes of Great Teachers.[223][226] Despite its claimed biographical intentions, the book is almost entirely a work of fiction.[223][226] In it, Hubbard relates in great detail a completely made-up physical exercise program which he claims Theon established for his daughter, involving "fishing, horseback-riding, and rowing".[227] He also claims that Theon taught Hypatia to "Reserve your right to think, for even to think wrongly is better than to never think at all."[227] Hubbard relates how, as a young woman, Hypatia traveled to Athens, where she was a student of the revered philosopher Plutarch of Athens.[227] All of this supposed biographical information, however, is completely fictional[227] and is not found in any ancient source.[227] Hubbard even attributes to Hypatia numerous completely fabricated quotations in which she is presented as espousing modern, rationalist views.[227] The cover illustration for the book, a drawing of Hypatia by artist Jules Maurice Gaspard showing her as a beautiful young women with her wavy hair tied back in the classical style, has now became the most iconic and widely reproduced image of her.[223][224][225]
Around the same time, Hypatia was adopted by feminists[228] and her life and death began to be viewed in the light of the women's rights movement.[228] The author Carlo Pascal claimed in 1908 that her murder was an anti-feminist act and brought about a change in the treatment of women, as well as the decline of the Mediterranean civilization in general.[229] Dora Russell, the wife of Bertrand Russell, published a book on the inadequate education of women and inequality with the title Hypatia or Woman and Knowledge in 1925.[230] The prologue explains why she chose the title:[230] "Hypatia was a university lecturer denounced by Church dignitaries and torn to pieces by Christians. Such will probably be the fate of this book."[231] Hypatia's death became symbolic for some historians. For example, Kathleen Wider proposes that the murder of Hypatia marked the end of Classical antiquity,[232] and Stephen Greenblatt observes that her murder "effectively marked the downfall of Alexandrian intellectual life".[233] On the other hand, Christian Wildberg notes that Hellenistic philosophy continued to flourish in the 5th and 6th centuries, and perhaps until the age of Justinian I.[234][235]







“Fables should be taught as fables, myths as myths, and miracles as poetic fantasies. To teach superstitions as truths is a most terrible thing. The child mind accepts and believes them, and only through great pain and perhaps tragedy can he be in after years relieved of them. In fact, men will fight for a superstition quite as quickly as for a living truth–often more so, since a superstition is so intangible you can not get at it to refute it, but truth is a point of view, and so is changeable.”—Made-up quote attributed to Hypatia in Elbert Hubbard's 1908 fictional biography of her, along with several other similarly spurious quotations[227]
Widespread falsehoods and misconceptions about Hypatia continued to proliferate throughout the late twentieth century.[226] Even though Hubbard's fictional biography in Little Journeys to the Homes of Great Teachers was probably only intended for children,[224] the scholar Lynn M. Osen relied on it as her main source in her influential 1974 biographical article about Hypatia in her book Women in Mathematics, published by the MIT Press in 1974.[226] Likewise, Fordham University used Hubbard's biography as the main source of information about Hypatia in their medieval history course.[226][223] The thirteenth and final episode of Carl Sagan's 1980 PBS series Cosmos: A Personal Voyage relates a heavily fictionalized retelling of Hypatia's death, which results in the "Great Library of Alexandria" being burned by militant Christians.[152] In actuality, though Christians led by Theophilus did indeed destroy the Serapeum in 391 AD, the Library of Alexandria had already ceased to exist in any recognizable form centuries prior to Hypatia's birth.[10] As a female intellectual, Hypatia became a role model for modern intelligent women[228] and two feminist journals were named after her:[228] the Greek journal Hypatia: Feminist Studies was launched in Athens in 1984,[228] and Hypatia: A Journal of Feminist Philosophy was launched in the United States in 1986.[228] In the United Kingdom, the Hypatia Trust has compiled a library and archive of feminine literary, artistic and scientific work since 1996.[231] An extension of the trust has established the Hypatia-in-the-Woods retreat in Washington State, where artistic, business and academic women can spend time to work on projects.[231]
Judy Chicago's large-scale art piece The Dinner Party awards Hypatia a table setting.[236][237] Hypatia's place setting is decorated with Coptic designs[237] and the head of a Hellenistic goddess forms the "H" in her name.[229] Along the runner of the table, more Hellenistic goddesses are shown weeping in horror over Hypatia's death.[229] Chicago, in her description of Hypatia's spot at the table, states that the social unrest leading to Hypatia's murder was the direct result of Roman patriarchy and the mistreatment of women[238] and that the unrest, which is still ongoing, can only be brought to an end through the restoration of the original, primeval matriarchy.[238] She further blames Cyril for having instigated the murder[229] and concludes that all of Hypatia's writings were burned in the Library of Alexandria when it was deliberately destroyed, apparently under the assumption that this was done many years later.[229] Major works of twentieth century literature contain references to Hypatia,[239] including Marcel Proust's stories "Madame Swann At Home" and "Within a Budding Grove" from In Search of Lost Time, and Iain Pears's The Dream of Scipio.[211]
Twenty-first century
Hypatia's life continues to be fictionalized by authors in many countries and languages.[240] In Umberto Eco's 2002 novel Baudolino, the hero falls in love with a half-satyr, half-woman, who is descended from a group of Hypatia's young female disciples, who fled after their teacher's murder.[241] These disciples set up a female-only community who "tried to keep alive what they had learned from their mistress... [living] apart from the world, to rediscover what Hypatia had really said."[241] All the women, who reproduce by "fecundation" with satyrs, are named Hypatia and are collectively known as "hypatias".[241] Charlotte Kramer's 2006 novel Holy Murder: the Death of Hypatia of Alexandria portrays Cyril as an archetypal villain without an ounce of good.[242] Hypatia is repeatedly described as brilliant and beloved[243] and she humiliates Cyril by demonstrating that she knows more about the Christian scriptures than he does.[242] Ki Longfellow's novel Flow Down Like Silver (2009) invents an elaborate backstory for why Hypatia first started teaching.[244] Youssef Ziedan's novel Azazeel (2012) describes Hypatia's brutal murder through the eyes of the monk Hypa, who witnesses the incident.[245] In The Plot to Save Socrates (2006) by Paul Levinson and its sequels Unburning Alexandria (novelette, 2008; novel 2013) and Chronica, Hypatia turns out to have been a time-traveler from the twenty-first century United States.[246][247][248]
The 2009 film Agora, directed by Alejandro Amenábar and starring Rachel Weisz as Hypatia, is a heavily fictionalized dramatization of Hypatia's final years.[10][249][250] The film, which was intended to criticize contemporary Christian fundamentalism,[251] has had wide-ranging impact on the popular conception of Hypatia.[249] Unlike previous fictional adaptations, Agora emphasizes Hypatia's astronomical and mechanical studies rather than her philosophy, portraying her as "less Plato than Copernicus".[249] It also, more than any other previous portrayal, emphasizes the restrictions imposed on women by the early Christian church.[252] In one scene, Hypatia is sexually assaulted by one of her father's slaves, who has recently converted to Christianity,[253] and, in another scene, Cyril reads a verse from 1 Timothy 2:8-12 forbidding women from teaching.[253][254] Near the end of the film, Synesius warns Orestes that he must abandon his friendship with Hypatia in order to retain his faith as a Christian.[253] The film also portrays Cyril and his monks as swarthy, bearded men with covered heads clad in tattered black clothing,[253] resembling media portrayals of the Taliban.[253]
The film, however, also contains numerous historical inaccuracies:[10][253][255] It inflates Hypatia's achievements[152][255] and incorrectly portrays her as having discovered proof to support Aristarchus of Samos's heliocentric model of the universe,[152] for which there is no evidence that Hypatia ever even studied.[152] It also contains a scene based on the final episode from Carl Sagan's Cosmos in which a mob of Christians raid the Serapeum and burn all of the scrolls in it,[10] but leave the building itself largely intact, aside from knocking over a few statues.[10] In historical reality, the Serapeum probably did not have any scrolls in it at the time of its destruction[10][lower-alpha 3] and the Christians completely demolished the building to the ground.[10] The film also strongly implies that Hypatia is an atheist,[152] a notion directly contradictory to the surviving sources,[152] which all portray her as a devoted follower of the teachings of Plotinus, who taught that the goal of philosophy was "a mystical union with the divine."[152]
