To cut off the head of someone, especially as a method of execution or religious martyrdom.
From Latin decollatus, past participle of decollare (de- + collum, neck). This term comes from medieval and religious historical contexts describing executions.
Many early Christian saints were venerated as decollated martyrs, and in medieval art, you can see Saint John the Baptist depicted holding his own severed head—a powerful religious image that appeared in countless paintings.
