A Dictionary of Greek and Roman biography and mythology

(Νικόλαος Καβασίλας), archbishop of Thessalonica, was the nephew and successor of Neilus Cabasilas, with whom he has often been confounded. He lived about A. D. 1350. He first held a high office at the imperial court of Constantinople, and in that capacity he was sent in 1346 by Joannes, patriarch of Constantinople, to the emperor Cantacuzenus to induce him to resign the imperial dignity. In the year following he was sent by the emperor Cantacuzenus himself, who had then conquered and entered the city, to the palace of the empress Anna, to lay before her the terms of peace proposed by the conqueror. (Cantacuz. Hist. Byz. 4.39, &c., 14.16.) Nicolaus Cabasilas, who was a man of great learning, wrote several works, of which however only a few have been published, perhaps because he was, like his uncle, a vehement antagonist of the Latin church.
