A sphinx is a mythical creature with the head of a human and the body of a lion.

In Greek tradition, it has the head of a human, the haunches of a lion, and sometimes the wings of a bird. It is mythicised as treacherous and merciless. Those who cannot answer its riddle suffer a fate typical in such mythological stories, as they are killed and eaten by this ravenous monster. This deadly version of a sphinx appears in the myth and drama of Oedipus. Unlike the Greek sphinx, which was a woman, the Egyptian sphinx is typically shown as a man (an androsphinx). In addition, the Egyptian sphinx was viewed as benevolent, but having a ferocious strength similar to the malevolent Greek version and both were thought of as guardians often flanking the entrances to temples
