Kastria Kalavryta (KASS-tree-uh kuh-LAHV-ree-tuh). The Cave of the Lakes in the Greek district of Achaia. When the daughters of King Proetus of Tiryns were driven mad by the goddess Hera and roamed the countryside thinking they were cows, it is said that they took refuge in the Cave of the Lakes. Here the seer Melampus cured them of their mania.
