The sistrum is an ancient Egyptian instrument that played an important role in rituals to worship goddesses like Bestet and Hathor, and was also essential to ceremonies meant to avert flooding of the Nile river. You could also use your sistrum to scare away Set, the potentially dangerous “god of the desert, storms, disorder, violence and foreigners.”
The instrument consists of a U-shaped frame on a handle. Rattles or bells are suspended on connectors between the two sides of the U. Shake the handle and the rattles make a sharp jingling noise.
