Her father Danaus had moved in to rule Argos, which being in a state of drought was up for grabs. He had fifty daughters and decided to send them off in search for water. Probably because it was cheaper that way.
AMYMONE was one of those daughters, but having no luck she decided on a snooze instead. This did not improve her luck as she was molested by a satyr.
She shouted out to POSEIDON for help. He heard her plea and chased the satyr away with his trident. Then he just couldn’t avoid showing off to the fair maiden. He struck a rock with his trident and caused a spring of water to flow forth. Which was fair enough really seeing as it was him that caused the drought in the first place.
Never one to waste a chance with the fair sex, POSEIDON took over from where the satyr left off. The resulting son was called Nauplius and became founder of the city of Nauplia.
This is AMYMONE’s only claim to fame and no-one remembers what the other forty-nine daughters got up to.
