Since then, Heracles hated Lepreus, but when he came to Caucon's house after completing his twelve labors, Astydameia insisted that he reconcile with her son.
Lepreus then challenged Heracles to several friendly competitions, namely throwing a discus, drawing water, and seeing which of the two was the fastest eater, each having to consume a bull at a time.
After getting beaten in a drinking contest as well, he challenged Heracles to single combat and was killed during the match.
[4] Lepreus was said to have been buried in Phigalia, but the local inhabitants could not show his tomb.
He was also credited with having been the founder and eponym of the city Lepreum, though some believed that it was named after Leprea, daughter of Pyrgeus (that is, a possible sister of Lepreus), or simply after the skin disease known as λέπρα (leprā) which had once struck the local population.
