Drachm

Atarneus (also spelled Atarneos) was a small but strategically significant coastal city in Mysia, opposite Lesbos. It became notably associated with Hermias, a former slave who rose to become its ruler in the mid-fourth century BC and attracted a circle of Platonic philosophers — Aristotle among them, who married Hermias's niece and remained in the region for several years. The city's independent coinage, including small silver issues of this weight class, belongs to precisely the period of Hermias's rule before his capture and execution by the Persians around 341 BC.
