Mourzoufle had learnt to dread the courage of his enemies, and as strongly doubted the valour of his subjects; therefore, before risking any fresh warlike attempts, he determined to sue for peace, and demanded an interview with the leaders of the Crusaders. The lords and barons refused with horror to have an interview with the usurper of the throne, the murderer, the executioner of Alexius; but the love of peace, and the cause of humanity, induced the doge of Venice to consent to listen to the proposals of Mourzoufle. Henry Dandolo repaired in his galley to the point of the gulf, and the usurper, mounted on horseback, approached him as near as possible. The conference was long and animated. The doge required Mourzoufle to pay immediately five thousand pounds’ weight of gold, to aid the Crusaders in their expedition to Syria, and again to swear obedience to the Romish church. After a long altercation, Mourzoufle promised to give the Latins the money and assistance they demanded; but he could not consent to submit to the yoke of the Church of Rome.[121] The doge, astonished that, after having outraged all the laws of Heaven and nature, he should attach so much importance to religious opinions, casting a glance of contempt at Mourzoufle, asked him, if the Greek religion excused treachery and parricide?[122] The usurper, although much irritated, dissembled his anger, and was endeavouring to justify his conduct, when the conference was interrupted by some Latin horsemen. Mourzoufle, on his return to Constantinople, convinced that he must prepare for war, set earnestly about his task, and determined to die with arms in his hand. By his orders, the walls and towers that defended the city on the side of the port, were elevated many feet. He constructed upon the walls galleries of several stages, from which the soldiers might launch arrows and javelins, and employ balistas and other machines of war; at the top of each tower was placed a drawbridge, which, when lowered upon the vessels, might afford the besieged a means of pursuing their enemies, even to their own fleet.
