Ischys

In Greek mythology, Ischys (Ancient Greek: Ἰσχύς) was the son of Elatus and Hippea, and also the lover of Coronis. While Coronis was carrying Apollo's child, a (then white) crow told Apollo of the affair between Ischys and Coronis. Apollo was so angry that he glared at the crow (burning its feathers black) and asked his sister Artemis to kill Coronis.
