Castalia

Castalia, a fountain on the slope of Parnassus, a little above Delphi, in Phœis, sacred to Apollo and the Muses. All who visited the Delphian temple were wont to bathe their hair rore puro Castalie ('in the pure dew of Castalia'), but those who needed to be purified from murder bathed their whole body. Its waters, moreover, gave poetic inspiration to those who drank. The name was due to Castalia, daughter of Achelous, who threw herself into the fountain to escape the pursuit of Apollo.
