The Mabinogion Vol. 2

“ Then was the sword of Gwrnach brought to him. And Kai took a blue whetstone from under his arm, and asked him whether he would have it burnished white or blue. “Do with it as it seems good to thee, and as thou wouldest if it were thine own.” Then Kai polished one half of the blade and put it in his hand. “Will this please thee?” asked he. “I would rather than all that is in my dominions that the whole of it were like unto this. It is a marvel to me that such a man as thou should be without a companion.” “Oh! noble sir, I have a companion, albeit he is not skilled in this art.” “Who may he be?” ”

“ 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." ”

“ Nevertheless, he spoke words of comfort unto the messenger, saying:
“The great Kaikous is, I fear, puffed up with vanity, being not yet tried by either the cold or the heat of the world. And alas! I fear me, if what thou sayest be true, that the sun must revolve yet oft above his head ere he learneth the wisdom of the great; for unto true wisdom alone is it given to know when to strike and when to withhold the hand. Verily, he is like a child with a sword who thinketh the world and all therein must tremble, if he but upraiseth it.
