A Dictionary of Greek and Roman biography and mythology

(Ἐρωτιανός), or, as he is sometimes called, Herodianus (Ἠρωδιανός), the author of a Greek work still extant, entitled Τῶν παρʼ Ἱπποκράτει Λέξεων Συναγωγή, Vocum, quae apud Hippocratem sunt, Collectio. It is uncertain whether he was himself a physician, or merely a grammarian, but he appears to have written (or at least to have intended to write) some other works on Hippocrates besides that which we now possess (pp. 23, 208, ed. Franz). He must have lived (and probably at Rome) in the reign of the emperor Nero, A. D. 54-68, as his work is dedicated to his archiater, Andromachus.
