Calchas

Calchas was a Greek mortal.

Mythology
Calchas was a seer that aided the Trojans. He told Agamemnon that he had to sacrifice his daughter to please Artemis, whom he had offended in order to slow down the Greek ships from reaching Troy.

In the Iliad, Calchas discovered that in order for Apollo to stop the plague that he had sent among the Trojans, Chryseis had to be returned to her father, Chryses.

Calchas died either of shame after Mopsus beat him in a soothsaying contest or that he died of laughter when his day of death arrived and the prediction didn't materialize.
