The senators were at first greatly amazed, and then one of them said: “My lord, will you not send out messengers to search throughout all your lands for this maiden? Let each group of messengers search for one year, and return at the end of the year. So you shall live in good hope of success from year to year.” The messengers were sent out accordingly; but, however hard they tried, after three years three separate groups had brought back no news of the mysterious land and the beautiful maiden.

Then the groom of the chamber said to Maxen Wledig: “My lord, will you not go forth to hunt, as on the day when you had your dream?”

To this the emperor agreed, and rode to the place in the valley where he had slept. The groom of the chamber then said: “Will you not send messengers to the river’s source, my lord, and tell them to follow the track of your dream?”

And thirteen messengers were sent, who followed the river up until it issued from the highest mountain they had ever seen. “Behold our emperor’s dream!” they exclaimed, and they got to the top of the mountain, and descended the other side into a most beautiful and fertile plain, as Maxen Wledig had seen in his dream. Following the greatest river of all – probably it was the Rhine – the ambassadors reached the seaport on the North Sea, and found the fleet waiting with one ship larger than all the others; and they entered the ship and were carried to the fair island of Britain. Here they journeyed westward, and came to the mountainous land of Snowdon, where they could see the sacred isle of Mona, or Anglesey, and the fertile land of Arvon lying between the mountains and the sea. “This,” said the messengers, “is the land of our master’s dream, and in that fair castle we shall find the maiden who our emperor loves.”

So they went to the castle of Caernarvon, and in that impressive fortress was the great hall, with the two youths playing chess, the old man carving chessmen, and the maiden in her chair of gold. When the ambassadors saw the fair Princess Helena, they fell on their knees before her and said: “Empress of Rome, all hail!”

But Helena half rose from her seat in anger as she said: “What does this mockery mean? You seem to be men of gentle breeding,[11] and you are evidently messengers: why, then, do you mock me thus?”

But the ambassadors calmed her anger, saying: “Do not be angry, lady: this is no mockery, for the Emperor of Rome, the great lord Maxen Wledig, saw you in a dream, and he swore to marry none but you. Which, therefore, will you choose, to accompany us to Rome, and there be made empress, or to wait here until the emperor can come to you?”

The princess thought deeply for a time, and then replied: “I would not be too credulous, or too hard of belief. If the emperor loves me and would like to marry me, let him find me in my father’s house, and make me his bride in my own home.”

After this the messengers returned to the emperor in haste. When they reached Rome and informed Maxen Wledig of the success of their mission he at once gathered his army and marched across Europe towards Britain. He conquered Britain and eventually reached the fair country of Snowdon. He entered the castle and saw, at last, with his own eyes first the two youths, Kynon and Adeon, playing chess, then their father, Eudav, the son of Caradoc, and then his beloved, beautiful Helena, daughter of Eudav.

“Empress of Rome, all hail!” Maxen Wledig said; and the princess bent forward in her chair and kissed him, for she knew he was her destined husband. The next day they were married, and the Emperor Maxen Wledig gave Helena as dowry all Britain for her father, the son of Caradoc, and for herself three castles, Caernarvon, Caerlleon, and Caermarthen, where she lived in turn; and in one of them was born her son Constantine, the only British-born Emperor of Rome. To this day in Wales the old Roman roads that once connected Helena’s three castles are known as “Sarn Helen.”
