The Mabinogion — Kilhwch and Olwen (1877)
“ Then said Kai, "Gwrhyr Gwalstawt Ieithoedd, go thou and salute yonder man." "Kai," said he, "I engaged not to go further than thou thyself." "Let us go then together," answered Kai. Said Menw the son of Teirgwaedd, "Fear not to go thither, for I will cast a spell upon the dog, so that he shall injure no one." And they went up to the mound whereon the herdsman was, and they said to him, "How dost thou fare, O herdsman?" "No less fair be it to you than to me." "Truly, art thou the chief?" "There is no hurt to injure me but my own." ”
