These rare ‘false’ amulets are barely decribed 1. Hypocephali are small discs generally made of stuccoed linen. They were placed under the heads of the deceased. The circle symbolized the Eye of Re and was believed to magically cause the head and body to be enveloped in light. The scenes painted on them relate to ideas of ressurection, connecting them with the Osirian myth and the Book of the Dead
