SELKET (Selqet, Serket, Serqet)
Selket was the goddess of scorpians and magic. She was depicted in the form of a woman with a scorpian on her head.
Her roles in Egyptian mythology were many, mostly as a beneficial goddess. She watched over Qebehsenuef, one of the four sons of Horus, who in turn protected the intestines of the deceased. Other connections with the afterlife include her epithet, "Lady of the Beautiful Tent" which referred to her as a protector of the embalmer's tent. In the Afterlife she was said to watch over a dangerous twist in a pathway. She was also credited with guarding the snake, Apep following his imprisonment in the Underworld.
Selket was also associated with childbirth and nursing. Contrary to her typical benficial characterization, she was also related to the sun's scorching heat. In the Book of the Dead, she is a protector of the deceased and his teeth are identified with hers.
Magically, Selket was a protector from venomous bites. She was the patroness of magicians who dealt with poisoness bites. Suprisingly though, it was usually Isis who was invoked in spells against scorpion stings.
