Accordingly he called together from all quarters the master craftsmen in stone and wood, and bade them put forth their utmost skill to contrive some new kind of building that should stand for ever in memory of men so worthy. But all of them, mistrusting their own mastery in such a matter, were only able to meet him with a 'Nay.' Whereupon Tremounos, Archbishop of Caerleon, came unto the King and saith he: 'If man there be anywhere strong enow to carry out this ordinance into effect, let Merlin, Vortigern's prophet, set hand thereunto. For well I wot that never another man in thy kingdom is there that is brighter of wit than he, whether it be in foretelling that which shall be or in devising engines of artifice. Bid him come hither and set his wits to work, and I warrant he shall build thee a memorial to last!' Accordingly, when Aurelius had asked many questions about him, he sent divers messengers through the divers countries of the kingdom to find and fetch him; and after they had journeyed throughout the provinces they found him in the country of the Gewissi, at the fountain of Galabes that he wont to haunt, and, telling him what it was they wanted, brought him unto the King. The King received him gladly and bade him declare the future, being fain to hear marvellous things. Unto whom Merlin: 'Mysteries of such kind be in no wise to be revealed save only in sore need. For, and I were to utter them lightly or to make laughter, the spirit that teacheth me would be dumb and would forsake me in the hour of need.' At last, when he had in like manner denied them all, the King was not minded to ask him further about the future, but spake unto him of the work he did propose to construct. Unto whom Merlin:

'If thou be fain to grace the burial-place of these men with a work that shall endure for ever, send for the Dance of the Giants that is in Killaraus, a mountain in Ireland. For a structure of stones is there that none of this age could raise save his wit were strong enough to carry his art. For the stones be big, nor is there stone anywhere of more virtue, and, so they be set up round this plot in a circle, even as they be now there set up, here shall they stand for ever.'

Uther accordingly, seeing that they were ready fight, fell upon them straightway at the double-quick. Forthwith the Britons prevailed, and, his Irishmen all cut up and slain, forced Gilloman to flee for his life. When they had won the day they pressed forward to Mount Killaraus, and when they reached the structure of stones rejoiced and marvelled greatly. Whilst they were all standing around, Merlin came unto them and said: 'Now, my men, try what ye can do to fetch me down these stones! Then may ye know whether strength avail more than skill, or skill than strength.' Thereupon at his bidding they all with one accord set to work with all manner devices, and did their utmost to fetch down the Dance. Some rigged up huge hawsers, some set to with ropes, some planted scaling ladders, all eager to get done with the work, yet natheless was none of them never a whit the forwarder. And when they were all weary and spent, Merlin burst out on laughing and put together his own engines. At last, when he had set in place everything whatsoever that was needed, he laid the stones down so lightly as none would believe, and when he had laid them down, bade carry them to the ships and place them inboard, and on this wise did they again set sail and returned unto Britain with joy, presently with a fair wind making land, and fetching the stones to the ir burial-place ready to set up. When this was reported unto Aurelius, he sent messengers throughout the countries of Britain, bidding summon clergy and laity, and enjoining them when summoned to assemble at the Mount of Ambrius with rejoicing and honour to set up the stones again round the foresaid burial-place. Accordingly, in obedience to the edict, came pontiffs and abbots and folk of every single order or condition that were his subjects, and when all were met together on the day appointed, Ambrosius set the crown upon his own head and celebrated the 'Whitsuntide festival right royally, giving up the three following days running to the holiday. Meanwhile such honours as lacked a holder he distributed as bounties unto them of his household as rewards for their toil in his service. At that time two of the Metropolitan Sees, York, to wit, and the City of the Legions, were vacant without their shepherds. Wherefore, being minded to consult the common wish of his peoples, he gave York unto Samson, a man of high dignity and illustrious by the depth of his piety; and Caerleon unto Dubricius, whom the providence of God had before singled out as like to be right serviceable in that same place. And when he had settled these and other matters in his realm, he bade Merlin set up the stones that he had brought from Ireland around the burial-place. Merlin accordingly obeyed his ordinance, and set them up about the compass of the burial-ground in such wise as they had stood upon Mount Killaraus in Ireland, and proved yet once again how skill surpasseth strength.
