Ocythoe ("swift runner") is a variation of Ocypete (English translation: "swift wing") was one of the three harpies in Greek mythology. She was also known as Ocypode ("swift foot") or Okyupete. Ocypete was the swiftest of all the three harpies. According to the Greek mythological story even with her speed, she quickly ran out of energy and crash-landed on an island in the middle of the ocean and begged for mercy from the Gods. In Greek and Roman mythology the Harpies were creatures employed by the higher gods to carry out the punishment of crime. They were three in number : Aello, Ocypete, and Celaeno, or Podarge; and were said to be daughters of the giant Thaumas and the Oceanid nymph Electra.
