Arcadius of Antioch (Greek, Ancient (to 1453);: Ἀρκάδιος ὁ Ἀντιοχεύς) was a Greek grammarian who flourished in the 2nd century CE. According to the Suda,[1] he wrote treatises on orthography and syntax, and an onomasticon (vocabulary), described as "a wonderful production."[2]
Greek, Ancient (to 1453);: Περὶ τόνων (Peri tonon), an epitome of the major work of Herodian on general prosody in twenty books, was wrongly attributed to Arcadius; it is probably the work of Theodosius or a grammarian named Aristodemus. Though meager and carelessly assembled, it preserves the order of the original and so affords a foundation for its reconstruction.[2]
