One day the page of the chamber spake unto him; now, although he was page of the chamber, he was king of the Romans. “Lord,” said he, “all the people revile thee.” “Wherefore do they revile me?” asked the emperor. “Because they can get neither message nor answer from thee as men should have from their lord. This is the cause why thou art spoken evil of.” “Youth,” said the emperor, “do thou bring unto me the wise men of Rome, and I will tell them wherefore I am sorrowful.”
Then the wise men of Rome were brought to the emperor, and he spake to them. “Sages of Rome,” said he, “I have seen a dream. And in the dream I beheld a maiden, and because of the maiden is there neither life, nor spirit, nor existence within me.” “Lord,” they answered, “since thou judgest us worthy to counsel thee, we will give thee counsel. And this is our counsel; that thou send messengers for three years to the three parts of the world to seek for thy dream. And as thou knowest not what day or what night good news may come to thee, the hope thereof will support thee.”
So the messengers journeyed for the space of a year, wandering about the world, and seeking tidings concerning his dream. But when they came back at the end of the year, they knew not one word more than they did the day they set forth. And then was the emperor exceeding sorrowful, for he thought that he should never have tidings of her whom best he loved.
Then spoke the king of the Romans unto the emperor. “Lord,” said he, “go forth to hunt by the way thou didst seem to go, whether it were to the east, or to the west.” So the emperor went forth to the hunt, and he came to the bank of the river. “Behold,” said he, “this is where I was when I saw the dream, and I went towards the source of the river westward.”
And thereupon thirteen messengers of the emperor’s set forth, and before them they saw a high mountain, which seemed to them to touch the sky. Now this was the guise in which the messengers journeyed; one sleeve was on the cap of each of them in front, as a sign that they were messengers, in order that through what hostile land soever they might pass no harm might be done them. And when they were come over this mountain, they beheld vast plains, and large rivers flowing there through.
“Behold,” said they, “the land which our master saw.”
And they went along the mouths of the rivers, until they came to the mighty river which they saw flowing to the sea, and the vast city, and the many-coloured high towers in the castle. They saw the largest fleet in the world, in the harbour of the river, and one ship that was larger than any of the others. “Behold again,” said they, “the dream that our master saw.” And in the great ship they crossed the sea, and came to the Island of Britain. And they traversed the island until they came to Snowdon. “Behold,” said they, “the rugged land that our master saw.” And they went forward until they saw Anglesey before them, and until they saw Arvon likewise. “Behold,” said they, “the land our master saw in his sleep.” And they saw Aber Sain, and a castle at the mouth of the river. The portal of the castle saw they open, and into the castle they went, and they saw a hall in the castle. Then said they, “Behold, the hall which he saw in his sleep.” They went into the hall, and they beheld two youths playing at chess on the golden bench. And they beheld the hoary-headed man beside the pillar, in the ivory chair, carving chessmen. And they beheld the maiden sitting on a chair of ruddy gold.
The messengers bent down upon their knees. “Empress of Rome, all hail!” “Ha, gentles,” said the maiden, “ye bear the seeming of honourable men, and the badge of envoys, what mockery is this ye do to me?” “We mock thee not, lady; but the Emperor of Rome hath seen thee in his sleep, and he has neither life nor spirit left because of thee. Thou shalt have of us therefore the choice, lady, whether thou wilt go with us and be made empress of Rome, or that the emperor come hither and take thee for his wife?” “Ha, lords,” said the maiden, “I will not deny what ye say, neither will I believe it too well. If the emperor love me, let him come here to seek me.”
And by day and night the messengers hied them back. And when their horses failed, they bought other fresh ones. And when they came to Rome, they saluted the emperor, and asked their boon, which was given to them according as they named it. “We will be thy guides, lord,” said they, “over sea and over land, to the place where is the woman whom best thou lovest, for we know her name, and her kindred, and her race.”
And immediately the emperor set forth with his army. And these men were his guides. Towards the Island of Britain they went over the sea and the deep. And he conquered the Island from Beli the son of Manogan, and his sons, and drove them to the sea, and went forward even unto Arvon. And the emperor knew the land when he saw it. And when he beheld the castle of Aber Sain, “Look yonder,” said he, “there is the castle wherein I saw the damsel whom I best love.” And he went forward into the castle and into the hall, and there he saw Kynan the son of Eudav, and Adeon the son of Eudav, playing at chess. And he saw Eudav the son of Caradawc, sitting on a chair of ivory carving chessmen. And the maiden whom he had beheld in his sleep, he saw sitting on a chair of gold. “Empress of Rome,” said he, “all hail!” And the emperor threw his arms about her neck; and that night she became his bride.
