Who is the goat-god?

Answer 1

Throughout history Satan has been depicted as a goat that stands upright on his two back legs. "The lamb of God", is referred to as the people of the world making sacrifices to God. Showing the goat as a man is symbolic of being against God.

Answer 2

To the Greeks the entire race of goat-men were referred to as Satyr(s)

To the Latins (Romans) they were called Faun(s)

The most well known Satyr would be Pan.

In early Christian mythology Satan because associated with goats and being a goat man, probably due to the remark of Jesus Christ of:

Matthew 25:31-46 "When the Son of Man comes in his glory, and all the angels with him, he will sit on his throne in heavenly glory. All the nations will be gathered before him, and he will separate the people one from another as a shepherd separates the sheep from the goats. He will put the sheep on his right and the goats on his left.

Which is really unfortunate as goat are lovely creatures and some of us like them.

Answer 3

Pan is the goat god of nature. However the goat-like features we think of him having are actually representative of the Roman god Faunus, who was also a nature god and representative of the fertility and persistence of nature.
