On the coast of Elis, not far from the mouth of the river, there was a grotto sacred to them near modern Samiko, which was visited by persons afflicted with skin diseases.
[1] They were supposedly cured here by prayers and sacrifices to the nymphs, and by bathing in the river.
[2] The earliest known attestation of the cult of these nymphs was from the poet Moero in the 3rd century BCE.
[3] The river Anigrus (or Anigros) itself was a small stream in southern Elis that flowed down from Mount Lapithas and the mountains at Minthi to the Ionian Sea.
[3] The river and cave are now part of the thermal springs of Kaiafas.
