Question: What republic did  the person from whose writings The Ancalites are known play a role in the demise of?
Context: Jane Holt [née Wiseman] (c. 1682–1717) was a British actress, poet, and playwright.  She seems to have been from a modest labouring-class background and self-taught, but very little is known about her.  Her one known play, "Antiochus the Great, or, The Fatal Relapse", was successfully produced at the New Theatre, Lincoln's Inn Fields, in 1701.  She is thought to have been the "Mrs Holt" whose collection of verse, "A Fairy Tale Inscrib'd, to the Honourable Mrs. W—, with other Poems", was published in 1717. Adrastus of Aphrodisias (Greek: Ἄδραστος ὁ Ἀφροδισιεύς ; fl.  2nd century) was a Peripatetic philosopher who lived in the 2nd century AD.  He was the author of a treatise on the arrangement of Aristotle's writings and his system of philosophy, quoted by Simplicius, and by Achilles Tatius.  Some commentaries of his on the "Timaeus" of Plato are also quoted by Porphyry, and a treatise on the "Categories" of Aristotle by Galen.  None of these have survived.  He was a competent mathematician, whose writings on harmonics are frequently cited by Theon of Smyrna in the surviving sections of his "On Mathematics Useful for the Understanding of Plato".  In the 17th century, a work by Adrastus on harmonics, Περὶ Ἁρμονικῶν ("On Harmonics"), was said by Gerhard Johann Vossius to have been preserved, in manuscript, in the Vatican Library, although the manuscript appears to be no longer extant, if indeed this was not an error on Vossius' part. Dallas Albert Willard (September 4, 1935 – May 8, 2013) was an American philosopher also known for his writings on Christian spiritual formation.  Much of his work in philosophy was related to phenomenology, particularly the work of Edmund Husserl, many of whose writings he translated into English for the first time.  He was longtime Professor of Philosophy at The University of Southern California in Los Angeles, teaching at the school from 1965 until his death in 2013 and serving as the department chair from 1982 to 1985. Paul Brodeur (born May 16, 1931) is an investigative science writer and author, whose writings have appeared in The New Yorker, where he began as a staff writer in 1958.  He lives on Cape Cod.  For nearly two decades he researched and wrote about the health hazards of asbestos.  He has also written about the dangers of household detergents, the depletion of the ozone layer, microwave radiation and electromagnetic fields from power lines.  In 1992 he donated 300 boxes of papers accumulated during his research to the New York Public Library.  In 2010 he was informed that the NYPL had finished culling the papers it chose to retain in its collection.  Brodeur publicly objected, stating that the materials to be removed were essential to understanding his investigative process.  Science writer Gary Taubes has said Brodeur's writings on electromagnetic radiation are part of what inspired him to switch from writing about bad practices in physics to epidemiology and public health. Harold Brighouse (26 July 1882 – 25 July 1958) was an English playwright and author whose best known play is "Hobson's Choice".  He was a prominent member, together with Allan Monkhouse and Stanley Houghton, of a group known as the Manchester School of dramatists. Augustine of Hippo ( or ; 13 November 354 – 28 August 430) was an early North African Christian theologian and philosopher whose writings influenced the development of Western Christianity and Western philosophy.  He was the bishop of Hippo Regius in north Africa and is viewed as one of the most important Church Fathers in Western Christianity for his writings in the Patristic Era.  Among his most important works are "The City of God" and "Confessions." Gaius Julius Caesar (Latin: CAIVS IVLIVS CAESAR, ] , born: 13 July 100 BC – 15 March 44 BC), usually called Julius Caesar, was a Roman politician and general who played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire.  He is also known as a notable author of Latin prose. Sophie Doin (née Mamy), 1800 – 1846, was a French novelist and essayist whose writings contributed to the renewal of abolitionism in France during the 1820s.  She targeted abuses in the French colonies, most notably Guadeloupe and Martinique, where slavery continued for decades after the declaration of Haitian independence in 1804.  In her various antislavery writings, notably the novel La Famille noire, ou la Traite de l’esclavage [The Black Family, or the Slave Trade], she drew the French public's attention to the injustices committed by the slave system.  She called for a more humane treatment of Blacks, for the abolition of the slave trade, and for religious and practical education that would prepare slaves for eventual emancipation. The Ancalites were a tribe of Iron Age Britain in the first century BCE.  They are known only from a brief mention in the writings of Julius Caesar.  They may have been one of the four tribes of Kent, represented in Caesar by references to the "four kings of that region" and in the archaeological record by distinct pottery assemblages. Erik Davis (born June 12, 1967) is an American writer, scholar, journalist and public speaker whose writings have run the gamut from rock criticism to cultural analysis to creative explorations of esoteric mysticism.  He is perhaps best known for his book "Techgnosis: Myth, Magic and Mysticism in the Age of Information", as well as his work on California counterculture, including Burning Man, the human potential movement, and the writings of Philip K. Dick.
