Seth, who is also known as Set, is an Ancient Egyptian god who is regarded as the patron of Upper Egypt's 11th nome.  He was the brother of one of the gods, known as Osiris, and was an enemy of the god of the desert, known as Horus, who was the child of Isis. His cult eventually died out during the 1st millennium BC, and he was regarded as an evil god later.

The worship of Seth was originally held at Nubt, which was a predynastic center in Upper Egypt. It was also the site of a vast cemetery. The town lost its position as the pre-eminent center of Upper Egypt after the Kingdom of Egypt was unified in 3050 BCE, with the capital being Abydos and the royal god Horus.

He is one of the first five gods that were created by the union of the earth and the sky. His name is often translated as an "instigator of confusion," and he was associated with people and foreign lands.

Seth was depicted as a composite figure that had a canine body, a long, curved, pointed snout, and square-tipped ears. Various animals such as the aardvark, ass, fennec, jackal, oryx, and the long-snouted mouse have also been suggested as his form.

Even the ancient Egyptians rendered Seth's figure in various ways, which makes it look like a mythical composite. Some believe that it's a depiction of a giraffe, as the flat-topped horns resembled nosecones in the animal. The Egyptians depicted Seth in various ways, such as as as a donkey or a man wearing a mask made out of donkey's head. During the Late Period, Seth was also depicted as a mythological creature.

He is often depicted as a red-haired creature with a long, curly tail and a dog-like body that's referred to as the Seth Animal. Scholars claim that this mythological creature was inspired by the Saluki breed. Others maintain that it's a mythological creature that was only meant to represent Seth, whose other notable symbols included the racoons, crocodiles, tortoises, and the griffin.
