issued a challenge that if any of Scariano’s knights should dare to say that the war was just, he, the ambassador of the King of Tremicen, would be pleased to maintain the contrary and engage in mortal combat with that knight. From the resemblances just pointed out, are we not justified in challenging the statement that Tirant lo Blanch represents Roger de Flor? Tirant’s activities at Constantinople constitute the most important part of his career, and this part is said to be based on the Catalan-Aragonese expedition to Constantinople under the leadership of that famous Catalan hero. Let us examine closely the part of Muntaner’s _Chronica_ which treats of Roger de Flor and his expedition, in order that we may see how closely Martorell followed the facts connected with that glorious page in Catalan history. CHAPTER III ROGER DE FLOR’S CAREER AT CONSTANTINOPLE Roger de Flor, with many soldiers and adventurers from Catalonia and Aragon, had fought on the side of Frederick I of Aragon, while the latter was engaged in a war against Charles of Anjou, King of Naples, for the possession of the kingdom of Sicily. When the war was over, Roger and his companions in arms were without employment. He then conceived the plan of entering the service of the Emperor of Constantinople, who was hard pressed by the Turks. Accordingly he sent two trustworthy knights to the emperor, with instructions and full powers to act for him. He offered his services under the following conditions: that the emperor give him his niece in marriage; that he appoint him Magaduch of the empire; and that he pay to the soldiers who came with Roger a stipulated wage. He felt certain that the mission of his agents would be successful, and, even before these returned, was busy making preparations for the expedition. Finally they came back with the espousals duly signed and Roger’s appointment and commission as Magaduch. This title and position was equal to that of prince, and carried with it command of the soldiers of the empire and authority over the Admiral. Roger, with the assistance of King Frederick, gathered a fleet of thirty-six vessels, and in these, without counting the crews, women, and children, 1500 cavalry and 5000 infantry set sail. On arriving at Constantinople they were received with great joy. The marriage of Roger and the emperor’s niece was celebrated without delay. The Genoese who were fighting under the imperial banners were in an ugly mood when they saw with what cordial welcome their rivals were received. Roger’s men resented their insolence, and a bloody battle ensued in which 3000 Genoese were slain. The emperor watched the fight with pleasure, for the overbearing ways of the Genoese had long been a source of extreme vexation to him. Roger’s _almogávares_ wished to sack Pera, where the Genoese lived, and it was with difficulty that the new Magaduch restrained them.
