These creatures look exactly like humans except for one important detail: their faces are on their chests, because most of the Acephali do not have heads. The Acephali are said to have once been human, but they rebelled against the gods and to punish them the gods removed their heads. Those that managed to find their removed head carry it under their arm. They are said to live in Libya.
Acephali is the plural form of Acephalos. They are also known as the Akephale.
