Around the wide world, all cultures share a few key features. Anthropologists debate the precise extent, but the basics are always there. Language. Tools. Marriage. Family. Ritual. Music. And penis-stealing witches.
Nobody knows when the penis-stealing witches began their malign activities. Babylonian texts include sa-zi-ga, incantations against witchcraft-induced impotence. Ancient Chinese sources describe suo yang, the penis retracting into the body because of yin/yang imbalances. But the first crystal-clear reference was the Malleus Maleficarum, the 15th-century European witch-hunters’ manual. It included several chapters on how witches cast curses that apparently (though not actually) remove men’s penises.
