ACHARNÆ, the principal demus of Attica, sixty stadia north of Athens, inhabited by the tribe Cneis. The Acharnians carried on an extensive traffic in charcoal, which they prepared from the wood of Mount Parnes, not far distant. The district was fertile, and the population warlike. One of the plays of Aristophanes is entitled 'The Acharnians.'—See LEAKE's Attica, p. 35.
