From the book, Babywatching by Desmond Morris – “It started as an ancient Egyptian custom and there are wall carvings to prove it. It seems to have its origin in snake worship. The Egyptians believed that when the snake shed its skin, and emerged shiny and new again, it was undergoing rebirth. They reasoned that if, by shedding skin, the snake could become apparently immortal, then humans should follow suit. They made the simple equation: snakeskin = foreskin, and the operation began. From there it spread to many Semetic peoples, both Arabs and Jews adopting it and converting it into an act of religious faith. As the centuries passed, it became popular in other regions of the world for moral, medical, or hygenic reasons.”
