Mount Arganthonius

Mount Arganthonius or Arganthonios (Ἀργανθώνιος), or Arganthon (Ἀργανθών), or Arganthoneion, 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.

Its modern name is Samanli Daği.
