The condition of having two heads or being two-headed, either as a physical abnormality or in mythology.
From di- (two) + cephalus (Greek kephale, head) + -ism (condition/state). Medical and mythological term combining Greek roots.
Dicephalism fascinates scientists and mythmakers alike—two-headed animals are usually stillborn, but the condition appears in mythology (like the two-headed eagle) as a symbol of power!
