Hegesandridas[1] or Agesandridas[2] (Ancient Greek: Ἡγησανδρίδας or Ἀγησανδρίδας), son of a "Hegesander" or "Agesander", who could have been a member of the last Spartan embassy sent to Athens before the Peloponnesian War.
News of their being seen off Las of Laconia arrived in Athens at the time when the Four Hundred were building their fort of Eëtioneia on a promontory commanding Piraeus, and the coincidence was used by Theramenes as evidence of their treasonable intentions.
[5] Thucydides thought it possible that the movement was really made in concert with the Athenian oligarchs, but it is far more probable that Hegesandridas was merely prompted by the hope of profiting by the existing dissensions at play in Athens.
A great alarm went up on behalf of the threatened island of Euboea, and a fleet was hastily manned, which amounted to thirty-six galleys, and the Battle of Eretria began.
[6] But the new crews were inexperienced and poorly equipped; a stratagem of the Eretrians kept the soldiers at a distance, at the very moment when, in response to a signal from the town, the Spartan admiral moved to attack.
