[Footnote 23: I here begin to use, with freedom and confidence, the eight books of the Histoire de C. P. sous l'Empire des FranÁois, which Ducange has given as a supplement to Villehardouin; and which, in a barbarous style, deserves the praise of an original and classic work.] The Latin conquerors had been saluted with a solemn and early embassy from John, or Joannice, or Calo-John, the revolted chief of the Bulgarians and Walachians. He deemed himself their brother, as the votary of the Roman pontiff, from whom he had received the regal title and a holy banner; and in the subversion of the Greek monarchy, he might aspire to the name of their friend and accomplice. But Calo-John was astonished to find, that the Count of Flanders had assumed the pomp and pride of the successors of Constantine; and his ambassadors were dismissed with a haughty message, that the rebel must deserve a pardon, by touching with his forehead the footstool of the Imperial throne. His resentment [24] would have exhaled in acts of violence and blood: his cooler policy watched the rising discontent of the Greeks; affected a tender concern for their sufferings; and promised, that their first struggles for freedom should be supported by his person and kingdom. The conspiracy was propagated by national hatred, the firmest band of association and secrecy: the Greeks were impatient to sheathe their daggers in the breasts of the victorious strangers; but the execution was prudently delayed, till Henry, the emperor's brother, had transported the flower of his troops beyond the Hellespont. Most of the towns and villages of Thrace were true to the moment and the signal; and the Latins, without arms or suspicion, were slaughtered by the vile and merciless revenge of their slaves. From Demotica, the first scene of the massacre, the surviving vassals of the count of St. Pol escaped to Adrianople; but the French and Venetians, who occupied that city, were slain or expelled by the furious multitude: the garrisons that could effect their retreat fell back on each other towards the metropolis; and the fortresses, that separately stood against the rebels, were ignorant of each other's and of their sovereign's fate. The voice of fame and fear announced the revolt of the Greeks and the rapid approach of their Bulgarian ally; and Calo-John, not depending on the forces of his own kingdom, had drawn from the Scythian wilderness a body of fourteen thousand Comans, who drank, as it was said, the blood of their captives, and sacrificed the Christians on the altars of their gods. [25] [Footnote 24: In Calo-John's answer to the pope we may find his claims and complaints, (Gesta Innocent III. c. 108, 109:) he was cherished at Rome as the prodigal son.]
