ARCADIUS  , of

Antioch, Greek grammarian, flourished in the 2nd century A.U . According to Suidas, he wrote treatises on orthography and syntax, and an onomaticon (vocabulary), described as a wonderful production . An epitome of the great work of Herodian on general prosody in twenty books, wrongly attributed to Arcadius, is probably the work of Theodosius of Alexandria or a grammarian named Aristodemus . This epitome (Hepi Tbvwv) only includes nineteen books of the original work; the twentieth is the work of a forger of the 16th century . Although meagre and carelessly put together, it is valuable, since it preserves the order of the original and thus affords a trustworthy foundation for its reconstruction .
