15th-century Byzantine writers

John Argyropoulos (Greek: Ἰωάννης Ἀργυρόπουλος Ioannis Argyropoulos; Italian: Giovanni Argiropulo; surname also spelt Argyropulus, or Argyropulos, or Argyropulo; c. 1415 – 26 June 1487) was a lecturer, philosopher and humanist, one of the émigré Greek scholars who pioneered the revival of classical greek learning in 15th-century Italy.

Mordecai ben Eliezer Comtino (Hebrew: מרדכי כומטיאנו‎; lived at Adrianople and Constantinople; died in the latter city between 1485 and 1490) was a Talmudist and scientist.

George Sphrantzes, also Phrantzes or Phrantza (Greek: Γεώργιος Σφραντζής or Φραντζής; 1401 – c. 1478), was a late Byzantine Greek historian and Imperial courtier. He was an attendant to Emperor Manuel II Palaiologos, protovestiarites ("Lord of the Imperial Wardrobe") under John VIII Palaiologos, and a close confidant to Constantine XI Palaiologos. He was an eyewitness of the Fall of Constantinople in 1453, made a slave by the victorious Ottomans, but ransomed shortly afterwards. Sphrantzes served the surviving members of the Palaiologian family for the next several years until taking monastic vows in 1472. It was while a monk he wrote his history, which ends with the notice of Sultan Mehmed II's attempt to capture Naupaktos, which he dates to the summer of 1477; Sphrantzes is assumed to have died not long after that event.
