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.
