[Footnote 21: The pope acknowledges his pedigree, a nobili urbis RomÊ prosapi‚ genitores tui originem traxerunt. This tradition, and the strong resemblance of the Latin and Walachian idioms, is explained by M. D'Anville, (Etats de l'Europe, p. 258--262.) The Italian colonies of the Dacia of Trajan were swept away by the tide of emigration from the Danube to the Volga, and brought back by another wave from the Volga to the Danube. Possible, but strange!] The Bulgarians were malicious enough to pray for the long life of Isaac Angelus, the surest pledge of their freedom and prosperity. Yet their chiefs could involve in the same indiscriminate contempt the family and nation of the emperor. "In all the Greeks," said Asan to his troops, "the same climate, and character, and education, will be productive of the same fruits. Behold my lance," continued the warrior, "and the long streamers that float in the wind. They differ only in color; they are formed of the same silk, and fashioned by the same workman; nor has the stripe that is stained in purple any superior price or value above its fellows." [22] Several of these candidates for the purple successively rose and fell under the empire of Isaac; a general, who had repelled the fleets of Sicily, was driven to revolt and ruin by the ingratitude of the prince; and his luxurious repose was disturbed by secret conspiracies and popular insurrections.

[23] While Isaac in the Thracian valleys pursued the idle and solitary pleasures of the chase, his brother, Alexius Angelus, was invested with the purple, by the unanimous suffrage of the camp; the capital and the clergy subscribed to their choice; and the vanity of the new sovereign rejected the name of his fathers for the lofty and royal appellation of the Comnenian race. On the despicable character of Isaac I have exhausted the language of contempt, and can only add, that, in a reign of eight years, the baser Alexius [24] was supported by the masculine vices of his wife Euphrosyne. The first intelligence of his fall was conveyed to the late emperor by the hostile aspect and pursuit of the guards, no longer his own: he fled before them above fifty miles, as far as Stagyra, in Macedonia; but the fugitive, without an object or a follower, was arrested, brought back to Constantinople, deprived of his eyes, and confined in a lonesome tower, on a scanty allowance of bread and water. At the moment of the revolution, his son Alexius, whom he educated in the hope of empire, was twelve years of age. He was spared by the usurper, and reduced to attend his triumph both in peace and war; but as the army was encamped on the sea-shore, an Italian vessel facilitated the escape of the royal youth; and, in the disguise of a common sailor,
