In Egyptian mythology, Serket (Serqet, Selket) was a scorpion-goddess, shown as a beautiful woman with a scorpion poised on her head. Her creature struck death to the wicked, but she was also prayed to to save the lives of innocent people stung by scorpions; she was also viewed as a helper of women in childbirth. She is also depicted as binding up demons that would otherwise threaten Ra, and she sent seven of her scorpions to protect Isis from Set.
She was the protectress of Qebhsenuef, the son of Horus who guarded the intestines of the deceased. She was made famous by her statue from Tutankhamen's tomb, which was part of the collection which toured America in the 1970's.
