SCARABAEUS, n. The sacred beetle of the ancient Egyptians, allied to our familiar "tumble-bug." It was supposed to symbolize immortality, the fact that God knew why giving it its peculiar sanctity. Its habit of incubating its eggs in a ball of ordure may also have commended it to the favor of the priesthood, and may some day assure it an equal reverence among ourselves. True, the American beetle is an inferior beetle, but the American priest is an inferior priest.
2010 Update: A symbol of the sun, found in a mound of dung. The more plausible easter egg.
