Ἀγίας), the son of Agelochus and grandson of Tisamenus of Elea, was the Spartan seer of Lysander, who predicted that general's victory at the battle of Aegospotami in 404 BC.
[1] Some ancient writers considered Agias' prediction—that Lysander would capture the entire fleet except for ten triremes (which fled to Corcyra)--to have been the cause of the victory more than a mere prediction.
[2] Pausanias mentions seeing a bronze statue of Agias at the altar of Augustus in the marketplace in Sparta.
This was the first time in the history of Sparta that statues of living military commanders were created.
The statue of Agias is somewhat unique in that it was the only one created by Pison of Kalaureia.
