Abridged from Harpokration s.v. As we see there, Pasinos is the name of a man mentioned by Isocrates in chap.18 of his nineteenth speech, the Aeginetan Speech (Aiginetikos: web address 1). This Pasinos, otherwise unmentioned and unknown, captured the island of Paros in or after autumn 394 BCE. If an Athenian (which is not certain), he was perhaps acting as agent for Pharnabazos and/or Konon.
