Calchas is an Argive mantis, or "seer," dated to the Age of Legend, which is an aspect of Greek mythology. Calchas appears in the opening scenes of the Iliad, which is believed to have been based on a war conducted by the Achaeans against the powerful city of Troy in the Late Bronze Age.
Calchas presides at the sacrifice of Iphigeneia, the daughter of Agamemnon, as the divine price of the winds required to carry the fleet to Troy, in a peristyle fresco from Pompeii.
