It was used in dances and religious ceremonies, particularly in the worship of the goddess Hathor, with the U-shape of the sistrum's handle and frame seen as resembling the face and horns of the cow goddess.
Additionally, the goddess Bast is often depicted holding a sistrum, symbolizing her role as a goddess of dance, joy, and festivity.
The Sistrum was occasionally revived in 19th century western orchestral music, nowadays however it is replaced by its close modern equivalent, the tambourine.
The sistrum consists of a metal frame in the shape of an egg, fastened to a handle, frequently surmounted by a grotesque head or by a figure of the sacred lioness Sekhet.
The frame is crossed by four metal horizontal rods passing through holes large enough to allow them to rattle when the sistrum is shaken, the rods being prevented from slipping out altogether by little metal stops in the shape of a leaf; sometimes metal rings are threaded over the rods to increase the jingling.
This ancient instrument was extensively used by the priests in the temple of Isis to attract the attention of worshippers to different parts of the ritual.
