While she was still pregnant, she slept with a mortal man named Ischys and was subsequently killed by either the god or his sister Artemis for her betrayal.

After failing to heal her, Apollo rescued their unborn child by performing a caesarean section.

One time when Apollo was away performing his godly duties, Coronis fell in love with Ischys, son of Elatus.

[12] In Ovid's poem, it is a raven that informed Apollo of the affair, and he killed Coronis with his own arrow.

[11] Later, Apollo entrusted his son to Chiron, the wise centaur, who trained him more in medicine and hunting.

[16][10] According to a different version, Coronis gave birth to her son in Apollo's temple in the presence of the Moirai.

[17] According to Ovid, when Coronis was pregnant, Apollo had appointed a white raven to guard her before leaving.

Apollo sent Artemis to kill the couple and in anger, turned the raven black by scorching it as a punishment for being a tattletale and failing its duty.

Furthermore, Antoninus Liberalis calls the man Coronis left Apollo for "Alcyoneus" rather than Ischys.
