Eparchides of Oineis (Ἐπαρχίδης ὁ Οἰνηΐτης)

Life Eparchides of Oineis was a 4th-century BCE Athenian author, known only from a citation in the lexicographer Harpocration [1]. His name identifies him as coming from the deme of Oineis, part of the Athenian tribe Oineis in northern Attica [1, 2]. No further biographical details survive.

Works His sole attested work is On the Demes of Attica (Περὶ τῶν δήμων τῆς Ἀττικῆς), a lost prose treatise cited by Harpocration for information on Athenian civic subdivisions [1].

Significance Eparchides was a minor Atthidographer, a chronicler of Attic local history and institutions [3]. His work contributed specific details on Athenian deme organization, serving as a reference for later antiquarians, though its impact was far more limited than that of major figures in the tradition.
