Spain produced horses, mules, wool, oil, figs, wine, corn, honey, beer, flax, linen, beside mines of copper, silver, gold, quicksilver, tin, lead, and steel. Gaul was so cultivated that there was little waste land, and produced the same fruits and vegetables as at the present day. Its hams and sausages were much prized. Sicily was famous for wheat, Sardinia for wool, Epirus for horses, Macedonia for goats, Thessaly for oil, Boeotia for flax, Scythia for furs, and Greece for honey. Almost all the flowers, herbs, and fruits that grow in European gardens were known to the Romans--the apricot, the peach, the pomegranate, the citron, the orange, the quince, the apple, the pear, the plum, the cherry, the fig, the date, the olive. Martial speaks of pepper, beans, pulp, lentils, barley, beets, lettuce, radishes, cabbage sprouts, leeks, turnips, asparagus, mushrooms, truffles, as well as all sorts of game and birds. [Footnote: Martial, B. 13.] In no age of the world was agriculture more honored than before the fall of the empire. [Sidenote: Roads.] And all these provinces were connected with each other and with the capital by magnificent roads, perfectly straight, and paved with large blocks of stone. They were originally constructed for military purposes, but were used by travelers, and on them posts were regularly established. They crossed valleys upon arches, and penetrated mountains. In Italy, especially, they were great works of art, and connected all the provinces. Among the great roads which conveyed to Rome as a centre were the Clodian and Cassian roads which passed through Etruria; the Amerina and Flavinia through Umbria; the Via Valeria, which had its terminus at Alternum on the Adriatic; the Via Latina, which, passing through Latium and Campania, extended to the southern extremity of Italy; the Via Appia also passed through Latium, Campania, Lucania, Iapygia to Brundusium, on the Adriatic. Again, from the central terminus at Milan, several lines passed through the gorges of the Alps, and connected Italy with Lyons and Mayence on the one side, and with the Tyrol and Danubian provinces on the other. Spain and southern Gaul were connected by a grand road from Cadiz to Narbonne and Arles. Lyons was another centre from which branched out military roads to Saintes, Marseilles, Boulogne, and Mayence. In fact, the Roman legion could traverse every province in the empire over these grandly built public roads, as great and important in the second century as railroads are at the present time. There was an uninterrupted communication from the Wall of Antonius through York, London, Sandwich, Boulogne, Rheims, Lyons, Milan, Rome, Brundusium, Dyrrachium, Byzantium, Ancyra, Tarsus, Antioch, Tyre, Jerusalem--a distance of 3740 miles. And these roads were divided by milestones, and houses for travelers erected every five or six miles. [Sidenote: Commerce.] [Sidenote: Objects of ancient commerce.]
