[A. D. 665-689.] The western conquests of the Saracens were suspended near twenty years, till their dissensions were composed by the establishment of the house of Ommiyah; and the caliph Moawiyah was invited by the cries of the Africans themselves. The successors of Heraclius had been informed of the tribute which they had been compelled to stipulate with the Arabs; but instead of being moved to pity and relieve their distress, they imposed, as an equivalent or a fine, a second tribute of a similar amount. The ears of the zantine ministers were shut against the complaints of their poverty and ruin their despair was reduced to prefer the dominion of a single master; and the extortions of the patriarch of Carthage, who was invested with civil and military power, provoked the sectaries, and even the Catholics, of the Roman province to abjure the religion as well as the authority of their tyrants. The first lieutenant of Moawiyah acquired a just renown, subdued an important city, defeated an army of thirty thousand Greeks, swept away fourscore thousand captives, and enriched with their spoils the bold adventurers of Syria and Egypt.146 But the title of conqueror of Africa is more justly due to his successor Akbah. He marched from Damascus at the head of ten thousand of the bravest Arabs; and the genuine force of the Moslems was enlarged by the doubtful aid and conversion of many thousand Barbarians. It would be difficult, nor is it necessary, to trace the accurate line of the progress of Akbah. The interior regions have been peopled by the Orientals with fictitious armies and imaginary citadels. In the warlike province of Zab or Numidia, fourscore thousand of the natives might assemble in arms; but the number of three hundred and sixty towns is incompatible with the ignorance or decay of husbandry;147 and a circumference of three leagues will not be justified by the ruins of Erbe or Lambesa, the ancient metropolis of that inland country. As we approach the seacoast, the well-known titles of Bugia,148 and Tangier149 define the more certain limits of the Saracen victories. A remnant of trade still adheres to the commodious harbour of Bugia, which, in a more prosperous age, is said to have contained about twenty thousand houses; and the plenty of iron which is dug from the adjacent mountains might have supplied a braver people with the instruments of defence. The remote position and venerable antiquity of Tingi, or Tangier, have been decorated by the Greek and Arabian fables; but the figurative expressions of the latter, that the walls were constructed of brass, and that the roofs were covered with gold and silver, may be interpreted as the emblems of strength and opulence.
