"These knights are fled, but they will come again. Therefore, sir, I counsel you to send for all the knights that hold their lands of this castle, and make them swear to restore the old customs, and do away with the evil practices which these villanous knights have fostered." "That is good counsel," said Galahad. Then she brought him a horn of ivory, richly adorned with gold, and said,-- "Blow this horn loudly. It will be heard two miles and more from the castle, and all that hear it will come." [Illustration: Copyright 1901 by E. A. Abbey; from a Copely print copyright 1902 by Curtis and Cameron. SIR GALAHAD FIGHTING THE SEVEN SINS.] Galahad took the horn, and blew so loud a blast that the very trees shook therewith. Then he seated himself and waited to see what would come from the summons. As he sat there a priest came to him and said,-- "Sir knight, for seven years these brethren have held the castle, whose lord, Duke Lianor, they killed, and held his daughter prisoner; and by force they have kept all the knights of the castle under their power, and have acted as tyrants, robbing the common people of all they had, and taking tribute and demanding service from all the country round. Seven years ago the duke's daughter said to them, 'You shall not hold this castle for many years, for by one knight you shall be overcome.' 'Say you so,' they replied. 'Then shall never knight or lady pass this castle, but all that come shall stay or lose their heads, till comes that knight of whom you prophesy.' Therefore this is called the Maidens' Castle, since its tyrants have so long made war upon maidens." "Is the duke's daughter still here?" "No; she died three days after the castle was taken. But her younger sister and many other ladies are held prisoners." Soon afterwards the knights of the country began to flock in, in response to the bugle-call, and glad were they to find what had occurred. Galahad made them do homage and fealty to the duke's daughter, which they did with great willingness of heart. And when the next day dawned great news was brought in, for a messenger came to Galahad and told him that the seven felon brothers had been met by Gawaine, Gareth, and Uwaine, and all slain. "So ends their rule and power," said Galahad, fervently. "It is well done, and well are all here delivered." Then he commended them to God, and took his armor and horse, and rode away amid the prayers of those he had delivered. CHAPTER IV. THE TEMPTATION OF SIR PERCIVALE.
