Read "Garden of Priapus" at The Eldritch Dark:
Priapus is a fertility god from Greek mythology, perhaps best known for his permanent erection. Statues of Priapus are believe to have been common in Roman gardens.
The tranquility we might usually associate with a garden setting is slightly altered in this short poem from Clark Ashton Smith (CAS), wherein he adds an element of suspense: "Somewhere in the garden / Lurks the garden-god". The active verb "Lurks" suggest that the manifestation of the god in question is not an inanimate work of sculpture.
