A perirrhanterion was a decorative open basin of water for symbolically purifying oneself before entering the temenos (the sanctuary area), in ancient Greece and possibly before that time. There are similar rituals of symbolic cleansing with "holy water" in past and contemporary spiritual traditions throughout the world.
I am working with the idea of the vessel of spiritually purifying water, and striving for an ethereal beauty equal to the purpose. I don't know of an actual perirrhanteria form that involved these specific visual elements.
