The term 'Chief Roman God' refers to the three gods of the Roman pantheon: SOL, EROS, and AMOR. SOL was the god of the sun, and was associated with the power of life and death. EROS was the god of love and desire, and was often depicted as a winged cupid. AMOR was the god of beauty and fertility, and was often depicted as a young man with a bow and arrow. Together, these three gods represented the power of the Roman Empire.
