Mount Arganthonius
Mount Arganthonius or Arganthonios, or Arganthon, 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. The name is connected with the mythus of Hylas and the Argonautic expedition.
Its modern name is Samanli Daği.
