Philiscus of Abydos
Philiscus or Philiskos (Greek: Φιλίσκος) was a 4th-century BC Greek tyrant of the city of Abydos, on the Asian side of the Hellespont, and a hyparch ("vice-regent") and military commander of the Achaemenid satrap Ariobarzanes. He was sent by Ariobarzanes in 368 BCE as an Achaemenid emissary to Delphi, where the Greek cities at war between themselves had assembled for peace negotiations. Philiscus had probably been sent at the request of either Athens or Sparta, to help solve the conflicts between the Greek city-states.
