Muses in the Fountain at Villa Montalvo

In the courtyard behind the Villa I found this beautiful fountain. I loved the way the sculptor created these three ladies. One can only imagine the story behind their emotions. I'm going on a fact finding mission to find out, but for now I'll post the painting my imagination came up with. The fountain itself had layers of dried minerals of all colors running down the forms of the ladies.
It wasn't too much of a stretch for me to imagine them in flowing watercolors.

Here again is what Wikipedia has to say about how the Villa was named. Does it mention who these mysterious ladies may be? Perhaps...

Phelan named Villa Montalvo in honor of the popular 16th century Spanish writer Garci Ordonez de Montalvo. Montalvo coined the name "California" in one of his fables. In it he described an island rich with gold and jewels, peopled by Amazons ruled by a queen named Califia. The Amazons in the fable rode griffins, mythical winged guardians of precious treasure. Griffins can be found throughout the arts center grounds, standing guard over Phelan's precious gift.

Did I mention that on the left and right of the ladies are winged creatures?
