The financial activity which centred in the Forum was a consequence, not merely of the contract-system encouraged by the State and of the business of the banker and the money-lender, but of the great foreign trade which supplied the wants and luxuries of Italy and Rome. This was an import trade concerned partly with the supply of corn for a nation that could no longer feed itself, partly with the supply of luxuries from the East and of more necessary products, including instruments of production, from the West. The Eastern trade touched the Euxine Sea at Dioscurias, Asia Minor chiefly at Ephesus and Apamea, and Egypt at Alexandria. It brought Pontic fish, Hellenic wines, the spices and medicaments of Asia and of the Eastern coast of Africa, and countless other articles, chiefly of the type which creates the need to which it ministers. More robust products were supplied by the West through the trade-routes which came down to Gades, Genua and Aquileia. Hither were brought slaves, cattle, horses and dogs; linen, canvas and wool; timber for ships and houses, and raw metal for the manufacture of implements and works of art. Neither in East nor West was the product brought by the producer to the consumer. In accordance with the more recent tendencies of Hellenistic trade, great emporia had grown up in which the goods were stored, until they were exported by the local dealers or sought by the wholesale merchant from an Italian port. As the Tyrrhenian Sea became the radius of the trade of the world, Puteoli became the greatest staple to which this commerce centred; thence the goods which were destined for Rome were conveyed to Ostia by water or by land, and taken by ships which drew no depth of water up the Tiber to the city.[163] But it must not be supposed that this trade was first controlled by Romans and Italians when it touched the shores of Italy. Groups of citizens and allies were to be found in the great staples of the world, receiving the products as they were brought down from the interior and supplying the shipping by which they were transferred to Rome.[164] They were not manufacturers, but intermediaries who reaped a larger profit from the carrying trade than could be gained by any form of production in their native land. The Roman and Italian trader was to be inferior only to the money-lender as a stimulus and a stumbling-block to the imperial government; he was, like the latter, to be a cause of annexation and a fire-brand of war, and serves as an almost equal illustration of the truth that a government which does not control the operations of capital is likely to become their instrument.[165]
