GEOFFREY AND THE LEGENDS OF ARTHUR. Geoffrey of Monmouth was a Welshman, familiar from his youth with Celtic legends; also he was a monk who knew how to write Latin; and the combination was a fortunate one, as we shall see. Long before Geoffrey produced his celebrated History (_cir._ 1150), many stories of the Welsh hero Arthur [Footnote: Who Arthur was has never been determined. There was probably a chieftain of that name who was active in opposing the Anglo-Saxon invaders of Britain, about the year 500; but Gildas, who wrote a Chronicle of Britain only half a century later, does not mention him; neither does Bede, who made study of all available records before writing his History. William of Malmesbury, a chronicler of the twelfth century, refers to "the warlike Arthur of whom the Britons tell so many extravagant fables, a man to be celebrated not in idle tales but in true history." He adds that there were two Arthurs, one a Welsh war-chief (not a king), and the other a myth or fairy creation. This, then, may be the truth of the matter, that a real Arthur, who made a deep impression on the Celtic imagination, was soon hidden in a mass of spurious legends. That Bede had heard these legends is almost certain; that he did not mention them is probably due to the fact that he considered Arthur to be wholly mythical.] were current in Britain and on the Continent; but they were never written because of a custom of the Middle Ages which required that, before a legend could be recorded, it must have the authority of some Latin manuscript. Geoffrey undertook to supply such authority in his _Historia regum britanniae_, or History of the Kings of Britain, in which he proved Arthur's descent from Roman ancestors. [Footnote: After the landing of the Romans in Britain a curious mingling of traditions took place, and in Geoffrey's time native Britons considered themselves as children of Brutus of Rome, and therefore as grandchildren of Æneas of Troy.] He quoted liberally from an ancient manuscript which, he alleged, established Arthur's lineage, but which he did not show to others. A storm instantly arose among the writers of that day, most of whom denounced Geoffrey's Latin manuscript as a myth, and his History as a shameless invention. But he had shrewdly anticipated such criticism, and issued this warning to the historians, which is solemn or humorous according to your point of view: "I forbid William of Malmesbury and Henry of Huntingdon to speak of the kings of Britain, since they have not seen the book which Walter Archdeacon of Oxford [who was dead, of course] brought out of Brittany."
