“Castalia’s themes are art, creativity, joy, children and inspiration. Her symbols are cartoon characters and fountains. In Greek tradition, this Goddess embodies the force of artistic inspiration. Her power is so profuse that art often depicts Her simply as an ever-flowing fountain from which we can drink when our motivation wanes.
On this day in 1901, the legendary Walt Disney was born. During his life, Disney inspired millions of children with a Castalia-rich imagination and well-beloved cartoon characters. To remember this man and uplift Castalia’s childlike ability to awaken the artist within, watch a favorite Walt Disney film today, revealing in the wonder of it. Then get out and do something creative! Try drawing your own magical cartoon (this is just for you and the Goddess, so don’t worry about a lack of skill – the keynote today is having fun with your fancy).
To quaff this Goddess’s inspiration for any task you’re undertaking, find a water fountain and drink fully of it. Visualize the water filled with a color of light, to you, represents creativity. Also fill a small container with a secure top with some of this water and keep it with you. Carry Castalia’s power into the situation in which you need inspiration. Pour a little out before your meeting, artistic effort or speech to release Her power. Or sip a bit of it to wet your whistle and renew the magic.”

Patricia Monaghan told us that Castalia was “the power that resided in a spring on Mt. Parnassus, this Goddess was apparently a force of artistic inspiration, for the Muses (called ‘Castalides‘ in Her honor) made Her fountain a sacred place” (p. 81).
Wikipedia states: “Castalia, in Greek mythology, was a nymph whom Apollo transformed into a fountain at Delphi, at the base of Mount Parnassos, or at Mount Helicon. Castalia could inspire the genius of poetry to those who drank Her waters or listened to their quiet sound; the sacred water was also used to clean the Delphian temples. Apollo consecrated Castalia to the Muses (Castaliae Musae). The 20th century German writer Hermann Hesse used Castalia as inspiration for the name of the fictional province in his 1943 magnum opus, The Glass Bead Game.” 
Now how, I wondered, did this all come about? Apparently, Castalia, (the daughter of the river-god Achelous) was pursued by Apollo. She then threw Herself into a spring on Mount Parnassus, which took its name after Her. Well damn, didn’t something similar happen when Apollo pursued a nymph called Daphne? Only, She turned into a Bay laurel tree. I can’t help but wonder then if this is yet another example of Chastity vs. Lust. “The myth of Apollo and Daphne has been examined as a battle between chastity (Daphne) and sexual desires (Apollo). As Apollo lustfully pursues Daphne, She is saved through Her metamorphosis and confinement into the laurel tree which can be seen as an act of eternal chastity. Daphne is forced to sacrifice Her body and become the laurel tree as Her only form of escape from the pressures of Apollo’s constant sexual desires. Apollo takes Daphne’s eternal chastity and crafts himself a wreath out of Her laurel branches turning Her symbol of chastity into a cultural symbol for him and other poets and musicians.”  So, I can’t help but wonder; was this an appropriate example for women to follow? If being pursued by a man, sacrifice yourself to keep your chastity intact…only to be used and exploited in another way to satisfy other needs?
The actual spring that She threw Herself into was created when Pegasus struck his hoof against a rock at the base of Mount Parnassus and water gushed forth, creating a wellspring of divine inspiration for the gods of Olympus.
