The Magna Mater, or Mother of the Gods, was one of the most notorious Eastern deities introduce to Rome. Known as Cybele in Greece. She was said to be served by self- castrated eunuch Priests (galli) and she was given a temple right in the heart of Rome.
Here she wears a turreted crown which represents her role as protectress of the city. In her hands she holds a patera and tympanum. She is closely associated with lions and they often are shown standing by her or pulling her chariot.
