John Chortasmenos


John Chortasmenos was a Byzantine monk and bishop of Selymbria, who was a distinguished bibliophile, writer, and teacher.

Life

Chortasmenos is first attested as a notary of the patriarchal chancery in 1391. He continued to occupy this position until. At some point he became a monk, with the monastic name Ignatios. Eventually he was raised to metropolitan bishop of Selymbria, a post he held by 1431.

Work

An ardent bibliophile, Chortasmenos is notable both as a writer as well as a teacher, counting such luminaries as Mark of Ephesus, Bessarion and Gennadius Scholarius among his pupils. He was the author of philological, historical and philosophical works, as well as at least 56 surviving letters to various literati and to Emperor Manuel II Palaiologos. He wrote a hagiography of Constantine the Great and Helena of Constantinople, commentaries on John Chrysostomos and Aristotle, a treatise on hyphenation, as well as poems.
It has been suggested that he wrote a historical work, now lost, covering the period between the end of the history of Emperor John VI Kantakouzenos and the early 15th century, when the historians who wrote after the Fall of Constantinople started their works with. Herbert Hunger attributed to him an anonymous account of the Ottoman siege of Constantinople in 1394–1402, but this was rejected by Paul Gautier.

Library

At least 24 surviving manuscripts are known to have belonged to Chortasmenos' library. Among the more notable is the Juliana Anicia Codex of Dioscurides, which he had restored, rebound, and a table of contents and extensive scholia added in Byzantine Greek minuscule in 1406. Beside the same problem in Diophantus' manuscript next to which Fermat would later write his famous marginalia, Chortasmenos wrote, "Thy soul, Diophantus, be with Satan because of the difficulty of your other theorems and particularly of the present theorem."
