Constantinople, which at that age so justly despised the ignorance of the Latins. But the Byzantine nation was servile, solitary, and verging to a hasty decline: after the fall of Kiow, the navigation of the Borysthenes was forgotten; the great princes of Wolodomir and Moscow were separated from the sea and Christendom; and the divided monarchy was oppressed by the ignominy and blindness of Tartar servitude. The Sclavonic and Scandinavian kingdoms, which had been converted by the Latin missionaries, were exposed, it is true, to the spiritual jurisdiction and temporal claims of the popes; but they were united in language and religious worship, with each other, and with Rome; they imbibed the free and generous spirit of the European republic, and gradually shared the light of knowledge which arose on the western world.

The three great nations of the world, the Greeks, the Saracens, and the Franks, encountered each other on the theatre of Italy. The southern provinces, which now compose the kingdom of Naples, were subject, for the most part, to the Lombard dukes and princes of Beneventum; so powerful in war, that they checked for a moment the genius of Charlemagne; so liberal in peace, that they maintained in their capital an academy of thirty-two philosophers and grammarians. The division of this flourishing state produced the rival principalities of Benevento, Salerno, and Capua; and the thoughtless ambition or revenge of the competitors invited the Saracens to the ruin of their common inheritance. During a calamitous period of two hundred years, Italy was exposed to a repetition of wounds, which the invaders were not capable of healing by the union and tranquility of a perfect conquest. Their frequent and almost annual squadrons issued from the port of Palermo, and were entertained with too much indulgence by the Christians of Naples: the more formidable fleets were prepared on the African coast; and even the Arabs of Andalusia were sometimes tempted to assist or oppose the Moslems of an adverse sect. In the revolution of human events, a new ambuscade was concealed in the Caudine Forks, the fields of CannÊ were bedewed a second time with the blood of the Africans, and the sovereign of Rome again attacked or defended the walls of Capua and Tarentum. A colony of Saracens had been planted at Bari, which commands the entrance of the Adriatic Gulf; and their impartial depredations provoked the resentment, and conciliated the union of the two emperors.
