(Θωμᾶς).

1. Magister, a rhetorician and grammarian, who flourished about A. D. 1310.

He appears to have been a native of Thessalonica, and to have lived at the court of the emperor Andronicus Palaeologus I., and to have held the offices of marshal (Magister Officiorum) and keeper of the archives (Chartophylax); but he afterwards retired to a monastery, where he assumed the name of Theodidulus, and devoted himself to the study of the ancient Greek authors.
