All of the Egyptian Gods have half human forms and animal forms for the important gods, except Osiris and Set. Osiris and Set were brothers, Set in a fit of jealous rage, chopped Osiris into pieces and threw them into the Nile. Osiris’ wife Isis, fished the pieces out and put them back together, holding them in place using mummy wrappings.
Set is never shown in animal form, unlike Bast, Anubis, Ma’at, Isis, Horus, etc. Also, they all have an identifiable animal form, Bast is a cat, Anubis is a jackal, Horus is a falcon, so on and so on. Set does have an animal head, they call it the Set Bird, because it doesn’t resemble any African animals.
I have been interested in Ancient Egyptian history since I was about 7. I have even taught myself to poorly read hieroglyphics. The first time, I saw Set, I couldn’t figure out why everyone said he was a bird. His head doesn’t resemble a bird. It has massive mule like ears and a long snout with the ability to show facial expressions. The mouth is usually depicted as slightly open.
It looks like an aardvark. I have always thought it looked like an aardvark. https://www.nationalgeographic.com/animals/mammals/a/aardvark/
I have no clue why Egyptologists have proclaimed it was a bird for so long. And it might make sense for Set to be an Aardvark. Also, Set is one of the few gods depicted with visible fingernails and aardvarks have claws.
Just something to think about.
