'When Kyig Arthur refused to pay tribute to the Romans, Lucius Tiberius, by order of the Senate, published a decree for the Eastern kings to come with their forces, and assist in the conquest of Britain.

'After the necessary dispositions were made, upon the kalends of August, they began their march towards Britain; which, when Arthur had intelligence of, he committed the government of the kingdom to his nephew Modred, and queen Guanhumara, and marched with his army to Hamos' port, where the wind stood fair for him. But while he, surrounded with all his numerous fleet, was sailing joyfully with a brisk gale, it happened that about midnight he fell into a very sound sleep; and in a dream saw a bear flying in the air, at the noise of which all the shores trembled; also a terrible dragon flying from the west, which enlightened the country with the brightness of its eyes. When these two met, they began a dreadful fight; but the dragon with its fiery breath burned the bear, which often assaulted him, and threw him down scorched to the ground. Arthur, upon this awaking, related his dream to those that stood about him, who took upon them to interpret it, and told him that the dragon signified himself, but the bear, some giant that should encounter with him; and that the fight portended the duel that would be between them, and the dragon's victory the same that would happen to himself. But Arthur conjectured it portended something else, and that the vision was applicable to himself and the emperor. As soon as the morning,' after this night's sail, appeared, they found themselves arrived at the mouth of the river Barba. And there they pitched their tents, to wait the arrival of the kings of the islands, and the generals of the other provinces.

'In the meantime Arthur had news brought him that a giant of monstrous size was come from the shores of Spain, and* had forcibly taken away Helena, the niece of Duke Hoel, from her guard, and fled with her to the top of that which is now called Michael's Mount; and that the soldiers of the country, who pursued him, were able to do nothing against him.

'Arthur's dream was fulfilled by the slaughter of the giant.' - British History.
