Sheela-na-gigs (above) adorn many twelfth and thirteenth-century Romanesque churches, mainly in Ireland. They typically portray older women with lined, almond-shaped eyes and an incorrigible grin. But her most distinguishable trait is always her pose — squatting, her hands pulling apart her labia to expose her gaping vagina.

What a stone-cold hussy.

The meaning of the Sheela-na-gigs is still hotly debated. One theory is she is a pagan touchstone to protect mothers giving birth. Supposedly, women would touch the screaming vulva to make the baby come out.
