The Sphinx was a composite creature with the head of a woman, the body of a lion, the wings of a bird and a serpentine tail.
Noted for its treachery, merciless and vicious, the Sphinx would lie in wait for travelers, then pounce upon them and propose a riddle. If the ill-fortuned person could not answer the riddle correctly, he or she was devoured by the Sphinx. Sphinx is also the name given to an Egyptian variant, usually a more benign, protective figure, but noted for its solemn dignity and implacable nature.
Astrologically, Sphinx represents mystery, enigma, inscrutability, and impenetrable thoughts, plans or intentions; questions, missing information or data, the “unknown”; it can also indicate a riddle or puzzle to be solved, or any person or thing which defies understanding, particularly of its motivations, aims or goals.
