The taxes of the Athenians, so far as they affected commerce, consisted of a fifth, levied on the corn and other merchandize imported, and also on several articles which were exported from Athens. These duties were generally farmed. In an oration of Andocides, we learn that he had farmed the duty on foreign goods imported for a term of three years, at twelve talents annually. In consequence of these duties, smuggling was not uncommon. The inhabitants of the district called Corydale were celebrated for illicit traffic: there was a small bay in this district, a little to the north of Piræus, called. Thieves' Harbour, in which an extensive and lucrative and contraband trade was carried on; ships of different nations were engaged in it. Demosthenes informs us, that though this place was within the boundaries of Attica, yet the Athenians had not the legal power to put a stop to traffic by which they were greatly injured, as the inhabitants of Corydale, as well as the inhabitants of every other state, however small, were sovereigns within their own territory. In an oration of Isocrates an operation is described which bears some resemblance to that performed by modern bills of exchange. A stranger who brought grain to Athens, and who, we may suppose, wished to purchase goods to a greater amount than the sale of his grain would produce, drew on a person living in some town on the Euxine, to which the Athenians were in the habit of trading. The Athenian merchant took this draft; but not till a banker in Athens had become responsible for its due payment. The Athenian merchants were obliged, from the nature of trade in those ancient times, to be constantly travelling from one spot to another; either to visit celebrated fairs, or places where they hoped to carry on an advantageous speculation. We shall afterwards notice more particularly the Macedonian merchant mentioned by Ptolemy the Geographer, who sent his clerks to the very borders of China; and from other authorities we learn that the Greek merchants were accurately informed respecting the interior parts of Germany, and the course of most of the principal rivers in that country. The trade in aromatics, paints, cosmetics, &c., was chiefly possessed by the Athenians, who had large and numerous markets in Athens for the sale of these articles. Even in the time of Hippocrates, some of the spices of India were common in the Peloponnesus and Attica; and there is every reason to believe that most of these articles were introduced into Greece in consequence of the journeys of their merchants to some places of depôt, to which they were brought from the East.
