“Gods, gods, why do you punish me? Yes, no doubt it is upon me again, again this terrible, invincible affliction … this hemicrania which grips half the head with pain … without remedy, without escape … I must try not to move my head. …”.
() Late Latin hemicrania (“pain in one half of the head”), from Ancient Greek ἡμικρᾱνίᾰ (hemikrania), from ἡμι- (hēmi-, “hemi-, half”) + κρανίον (kranion, “skull”) (from whence also cranium). Cognate to megrim and migraine, which also derive from the Latin.
