In Greek mythology, the amphisbaena is a venomous serpent with two heads, one at either end of its body.
While early depictions show the amphisbaena as a simple snake with a head at each end of its body, many Medieval and later illustrations show them with two or more chicken-like feet. Some also have horns.
Amphisbaena are said to live in deserts and feast on ants. Its eyes are said to glow like candles, and both mouths are said to overflow with poison.
