HERODIANUS, AELIUS, called 6 Tx"tx6s, Alexandrian grammarian, flourished in the and century A.D. He early took up his residence at Rome, where he enjoyed the patronage of Marcus Aurelius (161-180), to whom he dedicated his great treatise on prosody. This work in twenty-one books (KotfoXuo) irpoa&dia) included also an account of the etymological part of grammar. The work itself is lost, but several epitomes of it have been preserved. His 'Eiri/nepw/xoi dealt with difficult words and peculiar forms in Homer. Herodianus also wrote numerous grammatical treatises, of which only one has come down to us in a complete form (Ilept povripovs Xeos, on peculiar style), articles on exceptional or anomalous words. Numerous quotations and fragments still exist, chiefly in the Homeric scholiasts and Stephanus of Byzantium. Herodianus enjoyed a great reputation as a grammarian, and Priscian styles him " maximus auctor artis grammaticae."
The best edition is by A. Lentz, Herodiani Technici reliquiae (18671870); a supplementary volume is included in Uhling's Corpus grammaticorum Graecorum; for further bibliographical information see W. Christ, Geschichte der griechischen Literalur (1898).
