Manuel Kalekas (d. 1410) was a monk and theologian of the Byzantine Empire.
Kalekas was a disciple of Demetrios Kydones. He lived in Italy, Crete and Lesbos where he translated the works of Boethius and Anselm of Canterbury into Greek.[1] Kalekas translated the Comma Johanneum into Greek from the Vulgate.
Kalekas was a unionist who sought to reconcile the Eastern and Western Churches. In 1390, he wrote a work castigating the Byzantines for their separation from the Western Church.
Kalekas returned to Constantinople in 1403 with the emperor Manuel II Palaiologos, but to his surprise, was not given a warm reception by his old friends. As a result, he was forced to seek refuge with the Dominicans at Mytilene, where he died in 1410.[2]
