VIII. The Greeks themselves, during this period of captivity and exile, must be considered as a foreign nation; the enemies, and again the sovereigns of Constantinople. Misfortune had rekindled a spark of national virtue; and the Imperial series may be continued with some dignity from their restoration to the Turkish conquest. IX. The Moguls and Tartars. By the arms of Zingis and his descendants, the globe was shaken from China to Poland and Greece: the sultans were overthrown: the caliphs fell, and the Cæsars trembled on their throne. The victories of Timour suspended above fifty years the final ruin of the Byzantine empire. X. I have already noticed the first appearance of the Turks; and the names of the fathers, of Seljuk and Othman, discriminate the two successive dynasties of the nation, which emerged in the eleventh century from the Scythian wilderness. The former established a splendid and potent kingdom from the banks of the Oxus to Antioch and Nice; and the first crusade was provoked by the violation of Jerusalem and the danger of Constantinople. From an humble origin, the Ottomans arose, the scourge and terror of Christendom. Constantinople was besieged and taken by Mahomet II., and his triumph annihilates the remnant, the image, the title, of the Roman empire in the East. The schism of the Greeks will be connected with their last calamities, and the restoration of learning in the Western world. I shall return from the captivity of the new, to the ruins of ancient Rome; and the venerable name, the interesting theme, will shed a ray of glory on the conclusion of my labors.

The emperor Heraclius had punished a tyrant and ascended his throne; and the memory of his reign is perpetuated by the transient conquest, and irreparable loss, of the Eastern provinces. After the death of Eudocia, his first wife, he disobeyed the patriarch, and violated the laws, by his second marriage with his niece Martina; and the superstition of the Greeks beheld the judgment of Heaven in the diseases of the father and the deformity of his offspring. But the opinion of an illegitimate birth is sufficient to distract the choice, and loosen the obedience, of the people: the ambition of Martina was quickened by maternal love, and perhaps by the envy of a step-mother; and the aged husband was too feeble to withstand the arts of conjugal allurements. Constantine, his eldest son, enjoyed in a mature age the title of Augustus; but the weakness of his constitution required a colleague and a guardian, and he yielded with secret reluctance to the partition of the empire. The senate was summoned to the palace to ratify or attest the association of Heracleonas, the son of Martina: the imposition of the diadem was consecrated by the prayer and blessing of the patriarch; the senators and patricians adored the majesty of the great emperor and the partners of his reign; and as soon as the doors were thrown open, they were hailed by the tumultuary but important voice of the soldiers. After an interval of five months, the pompous ceremonies which formed the essence of the Byzantine state were celebrated in the cathedral and the hippodrome; the concord of the royal brothers was affectedly displayed by the younger leaning on the arm of the elder; and the name of Martina was mingled in the reluctant or venal acclamations of the people. Heraclius survived this association about two years: his last testimony declared his two sons the equal heirs of the Eastern empire, and commanded them to honor his widow Martina as their mother and their sovereign.

When Martina first appeared on the throne with the name and attributes of royalty, she was checked by a firm, though respectful, opposition; and the dying embers of freedom were kindled by the breath of superstitious prejudice. "We reverence," exclaimed the voice of a citizen, "we reverence the mother of our princes; but to those princes alone our obedience is due; and Constantine, the elder emperor, is of an age to sustain, in his own hands, the weight of the sceptre. Your sex is excluded by nature from the toils of government. How could you combat, how could you answer, the Barbarians, who, with hostile or friendly intentions, may approach the royal city? May Heaven avert from the Roman republic this national disgrace, which would provoke the patience of the slaves of Persia!" Martina descended from the throne with indignation, and sought a refuge in the female apartment of the palace. The reign of Constantine the Third lasted only one hundred and three days: he expired in the thirtieth year of his age, and, although his life had been a long malady, a belief was entertained that poison had been the means, and his cruel step-mother the author, of his untimely fate. Martina reaped indeed the harvest of his death, and assumed the government in the name of the surviving emperor; but the incestuous widow of Heraclius was universally abhorred; the jealousy of the people was awakened, and the two orphans whom Constantine had left became the objects of the public care. It was in vain that the son of Martina, who was no more than fifteen years of age, was taught to declare himself the guardian of his nephews, one of whom he had presented at the baptismal font: it was in vain that he swore on the wood of the
