When they appealed to the oracle at Delphi the Pythian priestess accused Melanippus and Comaetho. The oracle ordered that they themselves should be sacrificed to Artemis, and that every year a sacrifice should be made to the goddess of the fairest youth and the fairest maiden. Because of this sacrifice the river flowing by the sanctuary of Triclaria was called Ameilichus ( relentless). Previously the river had no name.
