Was probably a 7th-cent. colony of *Andros (Thuc. 4. 84) near the narrowest point of the Akte prong of *Chalcidice, and thus close to the canal dug in 480 bce on the orders of *Xerxes I of Persia (Hdt. 7. 22; Thuc. 4. 109); at this time it was an important Persian base. It remained loyal to Athens for much of the 5th cent. (paying a normal tribute of 3 talents in the *Delian League), until 424 when it was famously seduced by the rhetoric of the Spartan *Brasidas (Thuc. 4.85–7 for the speech, a tour de force), though Thuc. also drily notes (4. 88) that the Acanthians were concerned for their grape-vintage which Brasidas had threatened to destroy. Thuc. 4. 124. 1 (separate mention of Acanthians and Chalcidians in Brasidas' army) implies that like *Torone, Acanthus was not at this time a member of the Chalcidic League (see chalcidice).
