Seth
(Sutekh, Setech, and Sutech)
The
ancient Egyptian god of chaos, the embodiment of hostility
and even of outright evil. He is also a god of war, deserts,
storms, and foreign lands.
As
the god of deserts he protects the caravans which travel
through the desert, but he also causes sandstorms which
bring him into conflict with the fertility god Osiris.
The two are adversaries and in the Osiris myths, Seth killed
his brother and scattered the remains all over Egypt.
Seth
belongs to the Ennead of Heliopolis
and is the son of Geb and Nut
(or Re and Nut). He is the brother
of Osiris, Isis, and Nephthys,
who is sometimes given as his consort, although Seth is
more commonly associated with the foreign, Semitic goddesses
Astarte and Anat.
During
the 3rd millenium BCE Seth replaced Horus
as the tutelary deity of the pharaohs, but the story of
Osiris' murder gained currency and Horus was restored to
his original status. The war that followed lasted eighty
years, during which Seth tore out Horus' left eye and Horus
tore off Seth's foreleg and testicles.
Eventually,
Horus emerged victorious, or was deemed the victor by the
council of the gods, and thus became the rightful ruler
of the kingdoms of Lower and Upper Egypt. Seth was forced
to return the eye of Horus and was either castrated or killed.
In other versions he went to live with the sungod Re, where
he became the voice of thunder.
In
the Book of the Dead, Seth is called "Lord of the Northern
Sky" and is held responsible for storms and cloudy weather.
Despite
his reputation, Seth has some good characteristics. He protects
the sun barge of Re during its nightly journey through the
underworld and he fights the snake-like monster Apep.
On the other hand, he was a peril for ordinary Egyptians
in the underworld, where he was said to seize the souls
of the unwary.
Seth
was portrayed as a man with the head of undeterminable origin,
although some see in it the head of an aardvark. He had
a curved snout, erect square-tipped ears and a long forked
tail. He was sometimes entirely in animal form with the
body similar to that of a greyhound.
Animals
sacred to this god where the dog, the jackal, the gazelle,
the donkey, the crocodile, the hippopotamus, and the pig.
There
was an important sanctuary at Ombos in Upper Egypt, his
reputed birthplace, and considered to be the home of his
cult. This cult was also prominent in the north-eastern
region of the Nile delta.
The
Greeks equated him with their Typhon.
