The sistrum is a musical rattling instrument that was popular in the cult of the goddess Hathor. Called a "seshsehet" in Egyptian, the name imitates the swishing sound the small metal disks made when the instrument was shaken. Priestesses and royal women participating in rituals and ceremonies at temples and shrines played the sistrum. 
The face of the goddess Hathor is depicted with cow ears on the handle of the rattle.
