_Wherefore, let this story of Merlin be a warning unto you, I pray you all. For, though I do not believe that Merlin intended that his talents of magic should do harm unto others, yet, because of his folly, they did as great harm as though he himself had designed to do evil by means of them. Yea; it is hard to tell whether the wickedness or the follies of men do the greater harm in the world; therefore seek to guard yourself well, not only against sin, but against folly and weakness likewise._ [Illustration: The Enchanter Merlin.] [Illustration: Sorcery.] Prologue. Upon a certain day King Arthur sat in the Royal Hall of Camelot with the Queen and all of his Court and all of her Court. And there was great joy and mirth at that place. [Sidenote: _A messenger cometh to the King at Camelot._] Whiles they sat there, there suddenly came an armed knight into the Hall, and his armor was all covered with blood and dust, and he had a great many wounds upon his body. Then all they who were at that place were astonished and affrighted at the aspect of that knight, for his appearance boded no good news to King Arthur. The knight-messenger came to where the King was, and he was nearly fainting with weakness and with the many wounds he had received, and he brought news unto those who were there present that five kings, enemies to King Arthur, had suddenly come into that land and that they were burning and harrying the country upon every side. And the knight-messenger said that these five kings were the King of Denmark, the King of Ireland, the King of Soleyse, the King of the Vale, and the King of Longtinaise. These had brought with them a great host and were laying waste the land all around about, so that all the realm was in sore travail and sorrow because of their devastations. Upon this news, King Arthur smote his palms together with great vehemence and cried out, “Alas! who would be a king! Will the time never come when these wars and disturbances shall cease and we shall have entire peace in this land!” Therewith he arose in great agitation and went out from that place, and all who were there were in sore trouble. So King Arthur immediately sent messengers to two friendly kings who were nearest to him--to wit, to King Pellinore and to King Uriens of Gore--and he bade them to come to his aid without any loss of time. Meantime he himself gathered together a large army with intent to go forth to meet his enemies forthwith. [Sidenote: _King Arthur asketh aid of King Uriens and of King Pellinore._] So he went forth and upon the third day he came with his army unto the forest of Tintagalon and there he stayed with intent to rest for a little until King Pellinore and King Uriens should have joined him.
