A person who practices cephalomancy; someone who claims to predict the future by examining heads or skulls.
From Greek kephalē (head) + mantis (prophet, diviner). This agent noun follows the classical pattern of naming practitioners of specific arts or sciences.
A cephalomant would have been taken quite seriously in ancient times—they filled the same role fortune tellers do today, but their 'evidence' was literally your head, which seemed logical when people thought the head held the secrets of fate.
