Castālia, in Greek myth, the nymph who, when pursued by Apollo, threw herself into the spring on Mount Parnassus near Delphi. The spring was held sacred to Apollo and the Muses. All who wished to consult the Delphic Oracle were required to purify themselves in its waters. It may still be seen a little to the north-east of Delphi. To the Romans, ‘drinking the waters of Castalia’ signified poetic inspiration, since Apollo was the god of poetry.
