The earlier Greeks believed that a state should be self-supporting, that the farmers should produce enough food, and the craftsmen everything needed in daily life. But from the time of Solon onwards this became increasingly difficult in Athens, for owing to the arrival of settlers who came from many different places, attracted by the possibilities of work in the growing state, the population increased, and it became impossible to produce enough food. This had a very important influence on Athens, for instead of being self-sufficing and secure within her own walls, she became dependent for her life on the food supplies, and especially on the corn, that came to her from Egypt and the Black Sea colonies, and in the time of war it was absolutely necessary that the routes to these places should be kept open. Very strict laws were passed to regulate the corn trade and to make sure that enough would always {202} be brought to Athens. No Athenian merchant might take corn to any other harbour than the Peiraeus, and none might leave Egypt or the Black Sea ports unless he had a certain amount of corn on board his ship. The fact that the Athenian merchant had to go to distant places for corn increased his trade in other articles. He was at home on the sea, and his many-oared ship passed swiftly over the waters of the Aegean, stopping at many places: at the ports of Ionian colonies, where he found his kinsfolk, eager to hear the latest news from the mainland and especially from Athens; at the ports of the Barbarians, where he rejoiced that he was a Greek and did not dwell amongst these strangers. The Athenian merchant sailed in his own ship, and beyond his final destination, generally had no definite route in mind. He was guided by the favourable winds, or by rumours of suitable trading ports where he would find good opportunities for exchanging his goods. He left Athens with oil, honey from Hymettus, and the far-famed Athenian pottery, the chief exports, and he exchanged these for the corn and fish of the Black Sea ports, the wool of Miletus, the perfumes and spices of Syria, the linen and papyrus and the all-important corn of Egypt, the wine of Chios, the cypress wood of Crete, the dates of Phoenicia, the rugs and cushions of Carthage; while in such ports as Carthage and Miletus he found articles which had reached these places by caravans from still more distant lands. In Carthage he obtained ivory and ebony from Africa, {203} and in Miletus richly woven carpets and rugs from Babylon. All this trade brought wealth to Athens, and it taught the quick Athenian mind, always alert and interested in any new thing, "new ways of enjoying life." V. ATHENIAN POTTERY
