SGG 6 offers a commented critical edition of the preserved grammatical fragments of Zoilus of Amphipolis, a grammarian, rhetorician and historian, who lived in the 4th century BCE and is known as the Homeromastix (“the Scourge of Homer”). His most renowned work was Against Homer’s Poetry in nine books, in which he pointed out inconsistencies, contradictions and errors in Homeric poetry, in line with the Zetemata-type studies. The importance of his Homeric exegesis is demonstrated by contemporaries (among whom Aristotle) and later grammarians’ efforts in trying to find solutions to the problems he had raised.
