Apollonius Eidographus

Apollonius Eidographus (Ancient Greek: Άπολλώνιος Εἰδογράφος) was a writer referred to by the Scholiast on Pindar respecting a contest in which Hiero won the prize.^[1] Some writers have thought he was a poet, but from the Etymologicum Magnum,^[2] it is probable that he was some learned grammarian. He was head of the Library at Alexandria, succeeding Aristophanes of Byzantium and succeeded by Aristarchus of Samothrace.^[3] He was called "eidographus" ("the classifier") because he classified lyric poems based on their musical modes.^[4][5]
