Cato, the censor, has justly called Sicily the magazine and nursing mother of the Roman people, who were supplied from thence with almost all their corn, both for the use of the city, and the subsistence of her armies: though we also find in Livy, that the Romans received no inconsiderable quantities of corn from Sardinia. But, when Rome had made herself mistress of Carthage and Alexandria, Africa and Egypt became her storehouses; for those cities sent such numerous fleets every year, freighted with corn, to Rome, that Alexandria alone annually supplied twenty millions of bushels: and, when the harvest happened to fail in one of these provinces, the other came in to its aid, and supported the metropolis of the world, which, without this supply, would have been in danger of perishing by famine. Rome actually saw herself reduced to this condition under Augustus; for there remained only three days’ provision of corn in the city: and that prince was so full of tenderness for the people, that he had resolved to poison himself, if the expected fleets did not arrive before the expiration of that time; but they came; and the preservation of the Romans was attributed to the good fortune of their emperour: but wise precautions were taken to avoid the like danger for the future.
When the seat of empire was transplanted to Constantinople, that city was supplied in the same manner: and when the emperour, Septimius Severus, died, there was corn in the publick magazines for seven years, expending daily 75,000 bushels in bread, for 600,000 men.
The ancients were no less industrious in the cultivation of the vine than in that of corn, though they applied themselves to it later: for Noah planted it by order, and discovered the use that might be made of the fruit, by pressing out and preserving the juice. The vine was carried by the offspring of Noah into the several countries of the world; but Asia was the first to experience the sweets of this gift; from whence it was imparted to Europe and Africa. Greece and Italy, which were distinguished in so many other respects, were particularly so by the excellency of their wines. Greece was most celebrated for the wines of Cyprus, Lesbos, and Chio; the former of which is in great esteem at present, though the cultivation of the vine has been generally suppressed in the Turkish dominions. As the Romans were indebted to the Grecians for the arts and sciences, so were they, likewise, for the improvement of their wines; the best of which were produced in the country of Capua, and were called the Massick, Calenian, Formian, Caecuban, and Falernian, so much celebrated by Horace. Domitian passed an edict for destroying all the vines, and that no more should be planted throughout the greatest part of the west; which continued almost two hundred years afterwards, when the emperour Probus employed his soldiers in planting vines in Europe, in the same manner as Hannibal had formerly employed his troops in planting olive trees in Africa. Some of the ancients have endeavoured to prove, that the cultivation of vines is more beneficial than any other kind of husbandry: but, if this was thought so in the time of Columella, it is very different at present; nor were all the ancients of his opinion, for several gave the preference to pasture lands.
