Arganthonius
Ἀργανθώνιος
Arganthonius (Ἀργανθώνιος, Ἀργανθών, Steph. s. v. Ἀργανθών: Adj. Ἀργανθώνειος), a mountain range in Bithynia, which forms a peninsula, and divides the gulfs of Cius and Astacus. The range terminates in a headland which Ptolemy calls Posidium: the modern name is Katirli, according to some authorities, and Bozburun according to others. The name is connected with the mythus of Hylas and the Argonautic expedition. (Strab. p. 564; Apollon. 1.1176.)
