Iconography
Rhea only appears in Greek art from the 4th century BC, when her iconography draws on that of Cybele; the two are therefore often indistinguishable; both can be shown on a throne flanked by lions or on a chariot drawn by two lions. In Roman religion, her counterpart Cybele was Magna Mater deorum Idaea, who was brought to Rome and was identified in Roman mythology as an ancestral Trojan deity. On a functional level, Rhea was thought equivalent to Roman Ops or Opis.
Most often Rhea's symbol is a pair of lions, the ones that pulled her celestial chariot and were seen often, rampant, one on either side of the gateways through the walls to many cities in the ancient world. The one at Mycenae is most characteristic, with the lions placed on either side of a pillar that symbolizes the goddess.
