Demetrios Chrysoloras

Demetrios Chrysoloras (; ) was a Byzantine politician and writer, who served under emperors Manuel II Palaiologos and John VII Palaiologos.

Life and works Born in the noble Chrysoloras family, his relationship with the more famous Manuel Chrysoloras is unclear. He was friends with Manuel II and from 1403 to 1408 he served as mesazōn in Thessaloniki, under John VII Palaiologos. The last datable event of his life is his participation in the synod that elected Patriarch Joseph II (1416). However, Vasilios Pasiourtides argued that he could have survived Manuel II (d. 1425).

Unlike Manuel Chrysoloras, Demetrios Chrysoloras was firmly against the Church union and wrote against the Latins, Thomism and Demetrios Kydones. He was in epistolary contact with Manuel II and the distinguished scholar John Chortasmenos.

Among his surviving works are six speeches for the festivals of Orthodoxy; a praise of St Demetrios, which he wrote during his time in Thessaloniki; a short treatise on the Hodegetria; two panegyrics to Manuel II, one of which in the form of an epistolary collection, and the other being a long letter that compares Manuel II to the ancient rulers of Rome; a dialogue against Kydones and Thomas Aquinas. While at Thessaloniki, he also composed the preambles for two acts issued by John VII. Many of his works are still unedited.
