Bastet, great cat goddess, has dominion over sex, fertility, marriage, magic, music, childbirth, prosperity, joy, dance, and healing - in short, the pleasures of life. She protects humans against infertility, dangers of childbirth, evil spirits, illness, and bodily injuries, especially those caused by venomous creatures. A tomb inscription says Bastet bestows "life, prosperity and health every day and long life and beautiful old age."
