Successive inroads had reduced the province of Africa to one third of the measure of Italy; yet the Roman emperors continued to reign above a century over Carthage and the fruitful coast of the Mediterranean. But the victories and the losses of Justinian were alike pernicious to mankind; and such was the desolation of Africa, that in many parts a stranger might wander whole days without meeting the face either of a friend or an enemy. The nation of the Vandals had disappeared: they once amounted to a hundred and sixty thousand warriors, without including the children, the women, or the slaves.
