Hypate

In Greek mythology, Hypate was one of the three Muses of the lyre that were worshipped at the Oracle at Delphi. Her name was also one of the names of the three chords of the lyre. Her sisters that were worshipped along with her were Nete and Mesi. These three muses were comparable to the original three, Aoide, Melete, and Mneme. Alternatively, they were Cephisso, Apollonis, and Borysthenis, which protrayed them as the daughters of Apollo.
