The Sphinx was a legendary monster from Greek mythology and tradition that unlike her Egyptian counterparts was almost universally described as a female.

The Sphinx existed to guard a specific mountain range in which she would ask travellers to solve her riddle, if they could not answer it she would kill them.

One day however the Sphinx's riddle was answered and in a fit of uncontrollable rage she threw herself from the mountain to her death - it is unknown if their was more than one Sphinx or if she was a unique figure in Greek mythology.
