Mithras as Zoroastrianism, ancient & modern, from Persia to Rome to London

Zoroastrianism is the doctrine of dualism, the belief that Good and Evil exist and are equal, an energy which is separated into two equal forces which oppose each other, and which formed the Universe. Whether Mithraism is Monotheistic (one god) or polytheistic (many gods) it is a dualism religion which forgets that the Sun must have been created by a higher intelligence and itself is not a god, likewise the gods or sun god must have been created and who are taking the worship for themselves or itself.
