Mount Arganthonius

Mount Arganthonius or Arganthonios (Ancient Greek: Ἀργανθώνιος), or Arganthon (Ἀργανθών),^[1] or Arganthoneion,^[2] was a mountain range in ancient Bithynia, which forms a peninsula, and divides the gulfs of Cius and Astacus. The range terminates in a headland which Ptolemy calls Posidium (modern Bozburun). The name is connected with the myths of Hylas and the Argonautic expedition.^[3][4]

Its modern name is Samanli Daği.^[5][2]
