The tempest of the Turkish arms soon burst on his head; and after the loss of Adrianople and Romania, he was enclosed in his capital, the vassal of the haughty Amurath, with the miserable hope of being the last devoured by the savage. In this abject state, PalÊologus embraced the resolution of embarking for Venice, and casting himself at the feet of the pope: he was the first of the Byzantine princes who had ever visited the unknown regions of the West, yet in them alone he could seek consolation or relief; and with less violation of his dignity he might appear in the sacred college than at the Ottoman _Porte_. After a long absence, the Roman pontiffs were returning from Avignon to the banks of the Tyber: Urban the Fifth, [8] of a mild and virtuous character, encouraged or allowed the pilgrimage of the Greek prince; and, within the same year, enjoyed the glory of receiving in the Vatican the two Imperial shadows who represented the majesty of Constantine and Charlemagne. In this suppliant visit, the emperor of Constantinople, whose vanity was lost in his distress, gave more than could be expected of empty sounds and formal submissions. A previous trial was imposed; and, in the presence of four cardinals, he acknowledged, as a true Catholic, the supremacy of the pope, and the double procession of the Holy Ghost. After this purification, he was introduced to a public audience in the church of St. Peter: Urban, in the midst of the cardinals, was seated on his throne; the Greek monarch, after three genuflections, devoutly kissed the feet, the hands, and at length the mouth, of the holy father, who celebrated high mass in his presence, allowed him to lead the bridle of his mule, and treated him with a sumptuous banquet in the Vatican. The entertainment of PalÊologus was friendly and honorable; yet some difference was observed between the emperors of the East and West; [9] nor could the former be entitled to the rare privilege of chanting the gospel in the rank of a deacon. [10] In favor of his proselyte, Urban strove to rekindle the zeal of the French king and the other powers of the West; but he found them cold in the general cause, and active only in their domestic quarrels. The last hope of the emperor was in an English mercenary, John Hawkwood, [11] or Acuto, who, with a band of adventurers, the white brotherhood, had ravaged Italy from the Alps to Calabria; sold his services to the hostile states; and incurred a just excommunication by shooting his arrows against the papal residence. A special license was granted to negotiate with the outlaw, but the forces, or the spirit, of Hawkwood, were unequal to the enterprise: and it was for the advantage, perhaps, of PalÊologus to be disappointed of succor, that must have been costly, that could not be effectual, and which might have been dangerous. [12] The disconsolate Greek [13] prepared for his return, but even his return was impeded by a most ignominious obstacle. On his arrival at Venice, he
