Thomas Magister
A rhetorician and grammarian, about A.D. 1310. He was a native of Thessalonica, and lived
at the court of the emperor Andronicus Palaeologus I., where he 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
Theodūlus, and devoted himself to the study of the
ancient Greek authors. His chief work, which has come down to us, is a lexicon of Attic words
(
Κατὰ Ἀλφάβητον Ὀνομάτων Ἀττικῶν Ἐκλογαί),
compiled from the works of the elder grammarians, such as Phrynichus, Ammonius, Herodian, and
Moeris. It is edited by Ritschl
(Halle, 1831).
