Greek Anthology 6.214.2-4 (Simonides) -- but the headword Daretiou, extracted from it, is otherwise unattested, and problematical. Beckby's text of the Anthology prints dareikou= (cf. delta 72, delta 73). Arguably more attractive, though, is the idea of some connection -- if it could be made metrical here -- with the Damareteion, a gold coin which (according to Diodorus Siculus 11.26.3) was struck by Damarete, the wife of Gelon (gamma 113).
