Aelius Herodianus

Aelius Herodianus was a Greek grammarian of the 2nd century CE, the son of the grammarian Apollonius Dyscolus, who worked at Rome under the emperor Marcus Aurelius. He was one of the most influential scholars of the Greek language in antiquity, especially on questions of accentuation and word-forms, and his treatises were drawn upon by later grammarians for centuries. Much of his work survives only through quotation and abridgement.
