Apotropaic magic (from Greek "to ward off") or protective magic is a type of magic intended to turn away harm or evil influences, as in deflecting misfortune or averting the evil eye. Apotropaic observances may also be practiced out of superstition or out of tradition, as in good luck charms (perhaps some token on a charm bracelet), amulets, or gestures such as crossed fingers or knocking on wood. Many different objects and charms were used for protection throughout history. Apotropaic magical rituals were practiced throughout the ancient Near East and ancient Egypt. Fearsome deities were invoked via ritual in order to protect individuals by warding away evil spirits. In ancient Egypt, these household rituals (performed in the home, not in state-run temples) were embodied by the deity who personified magic itself, Heka. The two gods most frequently invoked in these rituals were the hippopotamus-formed fertility goddess, Taweret, and the lion-deity, Bes (who developed from the early apotropaic dwarf god, Aha, literally "fighter"). Objects were often used in these rituals in order to facilitate communication with the gods. One of the most commonly found magical objects, the ivory apotropaic wand (birth tusk), gained widespread popularity in the Middle Kingdom (ca. 1550 – 1069 BCE). These wands were used to protect expectant mothers and children from malevolent forces, and were adorned with processions of apotropaic solar deities. Likewise, protective amulets bearing the likenesses of gods and goddesses such as Taweret were commonly worn. Water came to be used frequently in ritual as well, wherein libation vessels in the shape of Taweret were used to pour healing water over an individual. In much later periods (when Egypt came under the Greek Ptolemies), stele featuring the god Horus were used in similar rituals; water would be poured over the stele and—after ritually acquiring healing powers—was collected in a basin for an afflicted person to drink.
