CHAPTER XX. How King Pellinore took Arthur’s horse and followed the Questing Beast, and how Merlin met with Arthur. Sir knight, said the king, leave that quest, and suffer me to have it, and I will follow it another twelvemonth. Ah, fool, said the knight unto Arthur, it is in vain thy desire, for it shall never be achieved but by me, or my next kin. Therewith he started unto the king’s horse and mounted into the saddle, and said, Gramercy, this horse is my own. Well, said the king, thou mayst take my horse by force, but an I might prove thee whether thou were better on horseback or I.—Well, said the knight, seek me here when thou wilt, and here nigh this well thou shalt find me, and so passed on his way. Then the king sat in a study, and bade his men fetch his horse as fast as ever they might. Right so came by him Merlin like a child of fourteen year of age, and saluted the king, and asked him why he was so pensive. I may well be pensive, said the king, for I have seen the marvellest sight that ever I saw. That know I well, said Merlin, as well as thyself, and of all thy thoughts, but thou art but a fool to take thought, for it will not amend thee. Also I know what thou art, and who was thy father, and of whom thou wert begotten; King Uther Pendragon was thy father, and begat thee on Igraine. That is false, said King Arthur, how shouldest thou know it, for thou art not so old of years to know my father? Yes, said Merlin, I know it better than ye or any man living. I will not believe thee, said Arthur, and was wroth with the child. So departed Merlin, and came again in the likeness of an old man of fourscore year of age, whereof the king was right glad, for he seemed to be right wise.
