Apep

Other Names: Apepi, Apophis, the Destroyer.
Patron of: evil and darkness.
Appearance: Apep was a huge serpent (or crocodile) which lived in the waters of Nun or in the celestial Nile
Description: Every day he attempted to disrupt the passage of the solar barque of Re. In some myths, Apep was an earlier and discarded sun-god himself. This helps to explain the snake's strength and his resentment of the daily journey of the sun. In Seth's battle for the throne of Egypt, he claimed that he was stronger than Horus because it was he that stood at the prow of the solar barque and defeated the enemies of Re.
Apep was a genuine threat to Re and his daily travels. At times he was successful and when this occurred stormy weather would occur. When Apep swallowed the barque, there was a solar eclipse.
Apep was known by many epithets, such as "the evil lizard", "the encircler of the world", "the enemy" and "the serpent of rebirth". He was not worshipped, he was feared, but was possibly the only god (other than The Aten during the Amarna period) who was considered to be all powerful. He did not require any nourishment and could never be completely destroyed, only temporarily defeated.
Apep led an army of demons that preyed on the living and the dead. To defeat this malevolent force a ritual known as "Banishing Apep" was conducted annually by the priests of Ra. An effigy of Apep was taken into the temple and imbued with all of the evil of the land. The effigy was then beaten, crushed smeared with mud and burned. Other rituals involved the creation of a wax model of the serpent which was ritually dismembered and the burning of a papyrus bearing an image of the snake. The "Book of Apophis" is a collection of magical spells from the New Kingdom which were supposed to repel or contain the evil of the serpent.
Apep was hated and feared by the Egyptians, but two of the Hyksos rulers chose his name as their coronation names (although they used a slightly different spelling).
