What is "pasithea"

In Greek mythology, Pasithea (, "relaxation"), or Pasithee, was one of the Charites (Graces), and the personification of relaxation, meditation. The Charites are usually said to be the daughters of Zeus and Eurynome, but Pasithea's parentage is given (by the poet Nonnus) as Hera and Dionysus. She was married to Hypnos, the god of sleep.
