Arcadius of Antioch (Ancient Greek: 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] Ancient Greek: 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.
