Context_1 : Hypatia ( ; ; Greek: Ὑπατία "Hupatía"; born 350–370; died 415 AD), often called Hypatia of Alexandria, was a Greek mathematician, astronomer, inventor, and philosopher in Egypt, then a part of the Eastern Roman Empire. She was the head of the Neoplatonic school at Alexandria, where she taught philosophy and astronomy. Context_2 : Theon Senior is a lunar impact crater that is located to the northwest of the crater Delambre, about 130 km east of Lade, and about 70 km south of D'Arrest. It forms a matching pair with Theon Junior, about two crater diameters to the south-southeast. The satellite crater Theon Senior A can be found to the north. Theon Senior is named for Theon of Smyrna, a 1st-century Greek mathematician and philosopher. Context_3 : Agora (Spanish: "Ágora" ) is a 2009 Spanish English-language historical drama film directed by Alejandro Amenábar and written by Amenábar and Mateo Gil. The biopic stars Rachel Weisz as Hypatia, a female mathematician, philosopher and astronomer in late 4th-century Roman Egypt, who investigates the flaws of the geocentric Ptolemaic system and the heliocentric model that challenges it. Surrounded by religious turmoil and social unrest, Hypatia struggles to save the knowledge of classical antiquity from destruction. Max Minghella co-stars as Davus, Hypatia's father's slave, and Oscar Isaac as Hypatia's student, and later prefect of Alexandria, Orestes. Context_4 : Abū Ṭāhir al-Silafī (born Isfahan in 472 AH/1079 CE; died Alexandria in 576/1180), was a leading scholar and teacher in sixth/twelfth-century Egypt. Among his many works is the "Mu‘jam al-safar" (the Dictionary of Travel), a biographical dictionary: 'covering from 511/1117 to 560/1164, the "Mu‘jam" can be regarded as a digest of intellectual life in late Fāṭimī Alexandria'. Al-Silafī ran the second madrasa to be built in Egypt (and the first Shāfi‘ī one there), built in Alexandria in 544/1149 on the order of Alexandria's then governor Shāfi‘ī al-‘Ādil b. Salār, vizier to Caliph al-Ẓāfir. It was named ‘Ādiliyya after its founder, but became popularly known as al-Silafiyya after its leading teacher. Probably in 512/1118, al-Silafī married Sitt al-Ahl bint al-Khalwānī; their daughter Khadīja (d. 623/1226) married the scholar Abu’l-Ḥarām Makkī b. ‘Abd al-Raḥmān al-Ṭrabulsī, whose son, Abu’l-Qāsim ‘Abd al-Raḥmān (born 570/1174), also became an important scholar in Alexandria. Context_5 : The Elements (Ancient Greek: Στοιχεῖα "Stoicheia") is a mathematical treatise consisting of 13 books attributed to the ancient Greek mathematician Euclid in Alexandria, Ptolemaic Egypt c. 300 BC. It is a collection of definitions, postulates, propositions (theorems and constructions), and mathematical proofs of the propositions. The books cover plane and solid Euclidean geometry, elementary number theory, and incommensurable lines. "Elements" is the oldest extant large-scale deductive treatment of mathematics. It has proven instrumental in the development of logic and modern science, and its logical rigor was not surpassed until the 19th century. Context_6 : Claudius Ptolemy ( ; Greek: Κλαύδιος Πτολεμαῖος , "Klaúdios Ptolemaîos" ] ; Latin: "Claudius Ptolemaeus" ; c. 170 ) was a Greco-Roman mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in the city of Alexandria in the Roman province of Egypt, wrote in Koine Greek, and held Roman citizenship. The 14th-century astronomer Theodore Meliteniotes gave his birthplace as the prominent Greek city Ptolemais Hermiou (Greek: Πτολεμαΐς ‘Ερμείου ) in the Thebaid (Greek: Θηβαΐδα [Θηβαΐς] ). This attestation is quite late, however, and, according to Gerald Toomer, the translator of his "Almagest" into English, there is no reason to suppose he ever lived anywhere other than Alexandria. He died there around AD 168. Context_7 : Antoninus (Greek: Ἁντωνῖνος ) was a Neoplatonist philosopher who lived in the 4th century. He was a son of Eustathius and Sosipatra, and had a school at Canopus, Egypt. He was an older contemporary of Hypatia who lived and worked nearby in Alexandria. He devoted himself wholly to his pupils, but he never expressed any opinion upon divine matters, and although Eunapius attributes this to Antoninus' piety, he also points out that Antoninus refrained from theurgic rites "perhaps because he kept a wary eye on the imperial views and policy which were opposed to these practices." His moral conduct is described as exemplary. He and his disciples were strongly attached to paganism; but he is said to have been able to see that its end was near at hand, and he predicted that after his death all the splendid temples of the gods would be changed into tombs: Context_8 : Theon of Alexandria ( ; Ancient Greek: Θέων ὁ Ἀλεξανδρεύς ; c. AD  335 – c. 405) was a Greek scholar and mathematician who lived in Alexandria, Egypt. He edited and arranged Euclid's "Elements" and wrote commentaries on works by Euclid and Ptolemy. His daughter Hypatia also won fame as a mathematician. Context_9 : The Alexandria Water Company (AWCO) is the water company of the city and the governorate (province) of Alexandria, Egypt. It was founded in 1860 as a private company and it operated as such for more than 100 years before it was nationalized under the rule of Gamal Abdel Nasser. At that time it became the Alexandria Water General Authority (AWGA), a department of Alexandria Governorate in charge of both water supply and sewerage. In 2004, through a country-wide sector reform it became a commercially oriented company under private law. The sewerage and wastewater treatment functions were transferred to a separate company, the Alexandria General Organization for Sanitary Drainage (AGOSD), later renamed to Alexandria Sanitary and Drainage Company (ASDCO). The water utility became a company under private law, reverted to its old name AWCO and gained some operational independence. Both AWCO and ASDCO are part of the government-owned Holding Company for Water and Wastewater, which owns all utilities in Egypt. AWCO serves 4.5 million inhabitants, a number that increases to 6 million during the summer season. The Alexandria water utility is one of the better-performing water service providers in Egypt, ranked fifth among 22 water utilities by the Egyptian Water Regulatory Authority in 2012/13. Context_10 : Aristaeus the Elder (Greek: Ἀρισταῖος ὁ Πρεσβύτερος ; 370 – 300 BC) was a Greek mathematician who worked on conic sections. He was a contemporary of Euclid, though probably older. Practically nothing of his life is known except that the mathematician Pappus of Alexandria refers to him as Aristaeus the Elder which presumably means that Pappus was aware of another later mathematician also named Aristaeus. Pappus gave Aristaeus great credit for a work entitled "Five Books concerning Solid Loci" which was used by Pappus but has been lost. He may have also authored the book "Concerning the Comparison of Five Regular Solids". This book has also been lost; we know of it through a reference by the Greek mathematician Hypsicles. fact_1 :  His daughter Hypatia also won fame as a mathematician. fact_2 : Hypatia ( ; ; Greek: Ὑπατία "Hupatía"; born 350–370; died 415 AD), often called Hypatia of Alexandria, was a Greek mathematician, astronomer, inventor, and philosopher in Egypt, then a part of the Eastern Roman Empire. Answer: Eastern Roman Empire
Output: Theon of Alexandria, was a Greek scholar and mathematician who lived in Alexandria, Egypt, his daughter was Hypatia, a Greek mathematician, astronomer, inventor, and philosopher in Egypt, then a part of which location?
