The two factions came to blows, some lives were lost, and Kildare attempted to seize the city by a sudden movement. The gates were, however, shut in time; but Ship Street, then outside the walls, was burned. The Geraldines wasted the Butler territory, and the Butlers in their turn ravaged Kildare and encamped in great force on the southern side of Dublin. A meeting of the two chiefs in St. Patrick's Cathedral was then arranged. A riot took place in the church, a flight of arrows was discharged, and Sir James, suspecting treason, barred himself into the Chapter-house. The Earl came to the door with offers of peace, and a hole was cut in the timber through which the rivals might shake hands. Sir James hesitated to risk his hand, but Kildare settled the question by putting in his own. The door was then opened, they embraced each other, and peace followed for a time. To make amends for the desecration of the church, the Pope ordered that the mayor should go barefoot through the city on Corpus Christi day, and this practice was continued till the Reformation. The door with the hole in it is still preserved, or was so until very lately.[57] [Sidenote: Perkin Warbeck lands 1491, but leaves the next year.] 'Ireland at this time,' says Ware, 'was as it were a theatre or stage on which masked princes entered, though soon after, their visors being taken off, they were expulsed the stage.' Perkin Warbeck landed at Cork late in 1491, or early in 1492, and was entertained by John Walters, an eminent merchant and future mayor. The citizens from the beginning insisted on regarding him as a royal personage, first as a son of Clarence, afterwards as a bastard of Richard III., and finally as Richard, Duke of York, Edward IV.'s younger son. Having adopted the latter character, Perkin wrote letters, extant in Ware's time, in which he sought help from the Earls of Desmond and Kildare. The former at once espoused his cause; the latter, according to his own account, would have nothing to do with 'the French lad.' Desmond joined Perkin in soliciting the aid of James IV. of Scotland, and he remained for about a year at Cork, learning English, but apparently without exciting any anxiety in England. Towards the close of 1492 he withdrew to France, where Charles VIII. received him as a prince, and where he was joined by disaffected Yorkists. Henry having made a successful campaign in France, Perkin was dismissed and went to Flanders, where Margaret of Burgundy acknowledged him as her nephew, and no doubt instructed him how to fill the part.[58] [Sidenote: Parliament of 1493.]
