The White Mount in which Bran's head was deposited is supposed to have been the Tower of London, described by a Welsh poet of the twelfth century as "The White Eminence of London, a place of splendid fame" (Guest, p. 392). VI. THE CASTLE OF THE ACTIVE DOOR This legend is mainly taken from different parts of Lady Charlotte Guest's translation of the "Mabinogion," with some additions and modifications from Rhys's "Hibbert Lectures" and "The Arthurian Legend." VIII. MERLIN In later years Merlin was known mainly by a series of remarkable prophecies which were attributed to him and were often said to be fulfilled by actual events in history. Thus one of the many places where Merlin's grave was said to be was Drummelzion in Tweeddale, Scotland. On the east side of the churchyard a brook called the Pansayl falls into the Tweed, and there was this prophecy as to their union:-- "When Tweed and Pansayl join at Merlin's grave, Scotland and England shall one monarch have." Sir Walter Scott tells us, in his "Border Minstrelsy," that on the day of the coronation of James VI. of Scotland the Tweed accordingly overflowed and joined the Pansayl at the prophet's grave. It was also claimed by one of the witnesses at the trial of Jeanne d'Arc, that there was a prediction by Merlin that France would be saved by a peasant girl from Lorraine. These prophesies have been often reprinted, and have been translated into different languages, and there was published in London, in 1641, "The Life of Merlin, surnamed Ambrosius, His Prophesies and Predictions interpreted, and their Truth made Good by our English Annals." Another book was also published in London, in 1683, called "Merlin revived in a Discourse of Prophesies, Predictions, and their Remarkable Accomplishments." VIII. LANCELOT The main sources of information concerning Lancelot are the "Morte d'Arthur," Newell's "King Arthur and the Table Round," and the publications of the Early English Text Society. See also Rhys's "Arthurian Legend," pp. 127, 147, etc. IX. THE HALF-MAN The symbolical legend on which this tale is founded will be found in Lady Charlotte Guest's translation of the "Mabinogion" (London, 1877), II. p. 344. It is an almost unique instance, in the imaginative literature of that period, of a direct and avowed allegory. There is often allegory, but it is usually contributed by modern interpreters, and would sometimes greatly astound the original fabulists. X. ARTHUR
