In "Chrysippus", Euripides develops backstory on the curse: Laius' sin was to have kidnapped Chrysippus, Pelops' son, in order to violate him, and this caused the gods' revenge on all his family. Laius was the tutor of Chrysippus, and raping his student was a severe violation of his position as both guest and tutor in the house of the royal family hosting him at the time. Extant vases show a fury hovering over the lecherous Laius as he abducts the rape victim. Furies avenged violations of good order in households, as can be seen most clearly in such texts as The Libation Bearers by Aeschylus.
