Walter, a Deacon of Oxford, it is said, had procured from Brittany a Welsh chronicle containing a history of the Britons from the time of one Brutus, a great-grandson of AEneas, down to the seventh century of our era.

From this, partly in translation and partly in original creation, Geoffrey wrote his "History of the Britons." Catering to the popular prejudice, he revived, and in part created, the deeds of Arthur and the Knights of the Round Table--fabulous heroes who have figured in the best English poetry from that day to the present, their best presentation having been made in the Idyls of the King, (Arthur,) by Tennyson.
The popular philosophy of Geoffrey's work is found in the fact, that while in Bede and in the Saxon Chronicle the Britons had not been portrayed in such a manner as to flatter the national vanity, which seeks for remote antecedents of greatness; under the guise of the Chronicle of Brittany, Geoffrey undertook to do this.

Polydore Virgil distinctly condemns him for relating "many fictitious things of King Arthur and the ancient Britons, invented by himself, and pretended to be translated by him into Latin, which he palms on the world with the sacred name of true history;" and this view is substantiated by the fact that the earlier writers speak of Arthur as a prince and a warrior, of no colossal fame--"well known, but not idolized....

That he was a courageous warrior is unquestionable; but that he was the miraculous Mars of the British history, from whom kings and nations shrunk in panic, is completely disproved by the temperate encomiums of his contemporary bards."[14] It is of great historical importance to observe the firm hold taken by this fabulous character upon the English people, as evinced by the fact that he has been a popular hero of the English epic ever since.

Spenser adopted him as the presiding genius of his "Fairy Queen," and Milton projected a great epic on his times, before he decided to write the Paradise Lost.
