Phul is an Olympian spirit in the grimoire known as the Arbatel de magia veterum. He rules over the Moon.
“ | Lunary concerns are under the government of PHUL, who truly transmutes all metals into silver, heals dropsy and provides Spirits of the Water, who serve men in a corporal [sic] and visible form; he also prolongs life to three hundred years. | ” |
— Arthur Edward Waite, The Book of Black Magic |
