The image of which animal was reflected in the aria of Mephistopheles from Charles Gounod's opera "Faust"?

False and misleading information! Aaron was a prophet like his brother Moses. Aaron followed the religion of his predecessors and father, the religion of Abraham a monotheistic religion. He worshipped the One and Only God, never constructed a calf for the Israelites to worship. The Israelites constructed the calf to worship and Aaron rejected their idea and refused to listen to him while Moses was away.
