An earl called the Bull, who tried to make Enid his handmaid; but, when she would neither eat, drink, nor array herself in bravery at his bidding, he smote her on the cheek; whereupon her lord and husband, Count Geraint, starting up, slew the russet-bearded earl in his own hall. (Tennyson Idylls of the King; Enid.)
