Editing John Chortasmenos

'''John Chortasmenos''' (Ιωάννης Χορτασμένος; 1370–1437) was a [[Byzantine]] monk, mathematician and astronomer.

Chortasmenos was a notary of the [[Patriarchate of Constantinople|patriarchal]] chancery, teacher of [[Mark of Ephesus]], [[Basilios Bessarion|Bessarion]] and [[Gennadius Scholarius]]. He was the author of philological, historical and philosophical works.

==Work==
In 1406 he had the [[Juliana Anicia Codex]] of [[Dioscurides]] restored, rebound, and a table of contents and extensive [[scholia]] added in Byzantine [[Greek minuscule]].<sup>[1]</sup>

Beside the same problem in [[Diophantus]]' manuscript next to which Fermat would later write his famous marginalia ([[Fermat's Last Theorem]]), Chortasmenos wrote, "Thy soul, Diophantus, be with Satan because of the difficulty of your other theorems and particularly of the present theorem."<sup>[2]</sup>
