Tympanum

In ancient Greece and Rome, the tympanon (τύμπανον) or tympanum, was a type of frame drum or tambourine. It was circular, shallow, and beaten with the palm of the hand or a stick. Some representations show decorations or zill-like objects around the rim. The instrument was played by worshippers in the rites of Dionysus, Cybele, and Sabazius.

The instrument came to Rome from Greece and the Near East, probably in association with the cult of Cybele. The first depiction in Greek art appears in the 8th century BC, on a bronze votive disc found in a cave on Crete that was a cult site for Zeus.
