Then king Arthur made ready his host in ten battles, and Nero was ready in the field afore the castle Terrabil with a great host, for he had ten battles, with many more people than Arthur had. Then Nero had the vaward with the most party of his people: and Merlin came to king Lot of the Isle of Orkney, and held him with a tale of prophecy till Nero and his people were destroyed. And there Sir Kay the seneschal did passingly well, that the days of his life the worship went never from him. And Sir Hervis de Revel did marvellous deeds with king Arthur, and king Arthur slew that day twenty knights and maimed forty. At that time came in the knight with the two swords, and his brother Balan, but they two did so marvellously that the king and all the knights marvelled of them, and all they that beheld them said they were sent from heaven as angels, or devils from hell: and king Arthur said himself they were the best knights that ever he saw, for they gave such strokes that all men had wonder of them. In the meanwhile came one to king Lot, and told him while he tarried there Nero was destroyed and slain with all his people. Alas, said king Lot, I am ashamed, for by my default there is many a worshipful man slain, for and we had been together there had been none host under the heaven that had been able for to have matched with us: this deceiver with his prophecy hath mocked me. All that did Merlin, for he knew well that if king Lot had been with his body there at the first battle, king Arthur had been slain and all his people destroyed. And well Merlin knew that one of the kings should be dead that day; and loth was Merlin that any of them both should be slain, but of the twain he had lever king Lot had been slain than king Arthur.
