You could think of her as the female equivalent of the Green Man.
If, as some contend, Sheela na Gig originally meant “Sheila of the Breasts,” she's a pretty classic example of, shall we say, upward displacement. Really, one has to admire such bald (!) candor.
To pagans, the body is hero: it's no surprise, then, that this minor motif of late medieval sculpture should have become something of a mascot to the new paganisms, with our signature revaluing, and re-spiritualization, of the body.
Gaze deeply into her mysteries, our Sheela.
There, suns are born, and constellations wheel.
Sheela na Gig
