The dream of Macsen Wledig
And the next day in the morning, the damsel asked her maiden portion. And he told her to name what she would. And she asked to have the Island of Britain for her father, from the Channel to the Irish Sea, together with the three adjacent Islands, to hold under the empress of Rome; and to have three chief castles made for her, in whatever places she might choose in the Island of Britain. And she chose to have the highest castle made at Arvon. And they brought thither earth from Rome that it might be more healthful for the emperor to sleep, and sit, and walk upon. After that the two other castles were made for her, which were Caerlleon and Caermarthen.
And one day the emperor went to hunt at Caermarthen, and he came so far as the top of Brevi Vawr, and there the emperor pitched his tent. And that encamping place is called Cadeir Macsen, even to this day. And because that he built the castle with a myriad of men, he called it Caervyrddin. Then Helen bethought her to make high roads from one castle to another throughout the Island of Britain. And the roads were made. And for this cause are they called the roads of Helen Luyddawc, that she was sprung from a native of this island, and the men of the Island of Britain would not have made these great roads for any save for her.
Seven years did the emperor tarry in this Island. Now, at that time, the men of Rome had a custom, that whatsoever emperor should remain in other lands more than seven years, should remain to his own overthrow, and should never return to Rome again.
So they made a new emperor. And this one wrote a letter of threat to Macsen. There was nought in the letter but only this.
"If thou comest, and if thou ever comest to Rome."
And even unto Caerlleon came this letter to Macsen, and these tidings. Then sent he a letter to the man who styled himself emperor in Rome. There was nought in that letter also but only this.
"If I come to Rome, and if I come."
And thereupon Macsen set forth towards Rome with his army, and vanquished France and Burgundy, and every land on the way, and sat down before the city of Rome.
A year was the emperor before the city, and he was no nearer taking it than the first day. And after him there came the brothers of Helen Luyddawc from the Island of Britain, and a small host with them, and better warriors were in that small host than twice as many Romans. And the emperor was told that a host was seen, halting close to his army and encamping, and no man ever saw a fairer or better appointed host for its size, nor more handsome standards.
And Helen went to see the hosts, and she knew the standards of her brothers. Then came Kynan the son of Eudav, and Adeon the son of Eudav, to meet the emperor. And the emperor was glad because of them, and embraced them.
Then they looked at the Romans as they attacked the city.
Said Kynan to his brother, "We will try to attack the city more expertly than this."
So they measured by night the height of the wall, and they sent their carpenters to the wood, and a ladder was made for every four men of their number. Now when these were ready, every day at mid-day the emperors went to meat, and they ceased to fight on both sides till all had finished eating. And in the morning the men of Britain took their food, and they drank until they were invigorated. And while the two emperors were at meat, the Britons came to the city, and placed their ladders against it, and forthwith they came in through the city.
