When food is scarce, hedgehogs retreat into underground dens for long periods, only to re-emerge in times of abundance. The Egyptians associated this behavior with rebirth and thus wore amulets in the form of hedgehogs or left figures such as this one in tombs. Also, according to the Ebers Medical Papyrus of the early Eighteenth Dynasty, hedgehog spines, when ground up and mixed with fat or oil, cured baldness.
