Calchas

In Greek mythology, Calchas (/ˈkælkəs/; Ancient Greek: Κάλχας, possibly meaning "bronze-man"), son of Thestor, was an Argive seer, with a gift for interpreting the flight of birds that he received of Apollo: "as an augur, Calchas had no rival in the camp". He also interpreted the entrails of the enemy during the tide of battle.
