Wearily they sailed on past the coast of Asia; they passed Sinope and the cities of the Amazons, the warlike women of the east, until at last they saw the "white snow peaks hanging glittering sharp and bright above the clouds. And they knew that they were come to Caucasus at the end of all the earth--Caucasus, the highest of all mountains, the father of the rivers of the East. And they rowed three days to the eastward, while the Caucasus rose higher hour by hour, till they saw the dark stream of Phasis rushing headlong to the sea and, shining above the treetops, the golden roofs of the Child of the Sun." How they reached home no man knows. Some say they sailed up the Danube River and so came to the Adriatic, dragging their ship over the snowclad Alps. Others say they sailed south to the Red Sea and dragged their ship over the burning desert of North Africa. More than once they gave themselves up for lost, "heartbroken with toil and hunger," until the brave helmsman cried to them, "Raise up the mast and set the sail and face what comes like men." After days and weeks on the "wide wild western sea" they sailed by the coast of Spain and came to Sicily, the "three-cornered island," and after numerous adventures they reached home once more. And they limped ashore weary and worn, with long, ragged beards and sunburnt cheeks and garments torn and weather-stained. No strength had they left to haul the ship up the beach. They just crawled out and sat down and wept, till they could weep no more. For the houses and trees were all altered, and all the faces which they saw were strange; and their joy was swallowed up in sorrow while they thought of their youth and all their labour, and the gallant comrades they had lost. And the people crowded round and asked them, "Who are you that sit weeping here?" "We are the sons of your princes, who sailed away many a year ago. We went to fetch the Golden Fleece and we have brought it back." Then there was shouting and laughing and weeping, and all the kings came to the shore, and they led the heroes away to their homes and bewailed the valiant dead. Old and charming as is the story of the Argonauts, it is made up of travellers' tales, probably told to the Greeks by the Phoenicians of their adventures on unknown seas. The wanderings of Ulysses by the old Greek poet Homer shows us that, though they seldom ventured beyond the Mediterranean Sea, yet the Greeks were dimly conscious of an outer world beyond the recognised limits. They still dreamt that the earth was flat, and that the ocean stream flowed for ever round and round it. There were no maps or charts to guide the intrepid mariners who embarked on unknown waters. The siege of Troy, famous in legend, was over, and the heroes were anxious to make their way home. Ulysses was one of the heroes, and he sailed forth from Asia Minor into the AEgean Sea. But contrary winds drove him as far south as Cape Malea.
