Calchas

Calchas, the famous soothsayer of the Greeks in the Trojan war, was the son of Thestor and Mycene. He foretold the length of the siege, and when the fleet was detained at Aulis by adverse winds, demanded the sacrifice of Iphigenia. He is said to have died at Colophon, from chagrin at being surpassed in soothsaying by one Mopsus.
