“The goddess Cybele was a great mother goddess adopted by Rome from Asia Minor. Her worship, like Isis, was popular amongst women. The worship of Cybele had emotional appeal, offering salvation and priests of the goddess castrated themselves in her service. A bronze castration clamp found in the Thames at London Bridge, is believed to have been used in the cult of Cybele. The clamp is decorated with busts of Cybele and her lover Attis while busts of other Roman deities represent the days of the week.” – Description.
