A sistrum is a musical instrument that originated in ancient Egypt, primarily used in religious ceremonies. It consists of a U-shaped metal frame with loose metal rods or jingles that produce sound when shaken. The sistrum was often associated with the goddess Hathor, who represented music, dance, and fertility. In addition to its use in Egypt, the sistrum has been found in various cultures throughout history, including Greece and Rome. It is typically made from materials like bronze or wood and serves both a musical and symbolic purpose, enhancing the spiritual atmosphere during rituals and celebrations.
