Chryses

In Greek mythology, Chryses was a priest of Apollo and father of Chryseis.

During the Trojan War, Agamemnon took Chryseis as a war prize and taunted Chryses when he attempted to buy her back. An oracle of Apollo then sent a plague sweeping through the Greek armies and Agamemnon was forced to give Chryseis back in order to end it.
