Leaving his animal atmosphere behind him, Pytheas returned to Orcas and from thence to Cantium. Instead of following his former track through the British Channel homeward, he turned to the eastward, and arrived, in a few days' sail, at the mouth of the Rhine. He found the country here inhabited by a race of fierce barbarians. Upon the shores of a vast gulf, beyond, dwelt the Teutons and the Guttones. In this gulf was an island named Abalcia, upon whose shores the waves deposited, in spring, immense quantities of yellow amber, which the inhabitants burned instead of wood, or sold for fuel to their neighbors the Teutons. Pytheas pursued his voyage as far as a river named Tanais, now supposed to be either the Elbe or the Oder. He considered this stream to be the eastern boundary of Celtica, in which he included Germania. He now turned his face homeward, and, coasting along the shores of Celtica and Iberia, arrived without accident or adventure at Massilia. He had sailed one hundred and eighty-six thousand stadia, or eleven thousand miles: the duration of the expedition was less than a year.
Geographers subsequent to Pytheas strove zealously to discredit his assertions. One denied the voyage altogether; another questioned the veracity of the narrative. Strabo was particularly hostile to Pytheas, whom he said he would prove "a liar of the first magnitude." He was thus led to make long quotations from his descriptions for the purpose of refuting them. As the original account given by Pytheas is not extant, the world is indebted to the skepticism of Strabo for all that it knows of one of the most interesting and daring maritime enterprises of antiquity.
In the year 326 before Christ, Alexander of Macedon, having accomplished the conquest of Persia, and having invaded Hindostan by the north, found himself compelled, by a mutiny of his troops, to arrest his course upon the eastern bank of the river Indus. He was here seized with a desire to explore the lower course of that river, and afterwards the southern shores of Asia, a tract of coast with which the Greeks were entirely unacquainted. The object of the expedition was partly exploration, and partly to convey a portion of the army back to Babylon upon the river Euphrates. The dangers of the enterprise and the improbability of success deterred the greater part of the naval officers from attempting it, as neither the Arabian Sea nor the Persian Gulf had ever been traversed before. Nearchus, the admiral of the fleet, proposed several candidates for the perilous honor, who variously excused themselves. Nearchus at last proffered his own services, which, after some hesitation, were accepted. This selection of a commander tranquillized the soldiers and sailors intended for the expedition; for they felt that Alexander would not have sent his intimate friend upon a voyage from which he would not be likely to return. The splendor of the preparations, the beauty of the vessels, the confidence of the officers, also went far towards dissipating their fears. At the word of Alexander, says a modern poet,—
"The pines descend; the thronging masts aspire;
The novel sails swell beauteous o'er the curves
Of Indus: to the moderator's song
The oars keep time, while bold Nearchus guides
Aloft the gallies. On the foremost prow
The monarch from his golden goblet pours
A full libation to the gods, and calls
By name the mighty rivers through whose course
He seeks the sea."
Alexander accompanied his fleet to the delta of the Indus, from whence he obtained a view of the gulf. He then returned to lead his men across Gedrosia, Caramania, and Persis to Babylon. Nearchus then set sail, after offering sacrifices to Neptune and Jupiter Salvator, and ordering a series of games and gymnastic exercises. The voyage thus undertaken was an event of real importance in the history of navigation: it opened a route between Europe and the extremities of Asia. It was the source of the discoveries made in later times by the Portuguese, and the primary, though remote, cause of the successful establishment of the British in India.
PLAN OF THE VOYAGE OF NEARCHUS.
At the very mouth of the river they met a formidable obstacle,—a rocky bar over which the waves broke with extreme violence. Through this bar, in its softest parts, they cut a canal one-third of a mile in length, and at high tide passed through it with the fleet. They had hardly reached the open ocean before a heavy gale drove them into an indentation of land protected by an island: to this natural harbor Nearchus gave the name of Alexander. Here he caused a camp to be laid out and entrenched, and remained for twenty-four days, the soldiers subsisting chiefly on shell-fish. When the gale abated they again embarked, meeting with constant adventures and difficulties upon their way. One day they would pass through huge menacing rocks, so near that they touched them with their oars on either side. On another they would be compelled, on landing for water, to ascend for miles into the interior before finding fresh-water sources. A storm caused two galleys and a vessel to founder, the crews of which, however, succeeded in swimming to shore. Nearchus caused his whole army to land at this point, for they needed repose, and his shattered fleet required repairs. He met with Leonatus, whom Alexander had detached from the main body of the army to follow the coasts and keep up a communication with Nearchus. Wheat was also sent to this spot by Alexander for the fleet, and each vessel took a supply sufficient for ten days. Nearchus exchanged such sailors and soldiers as had proved inefficient, for fresh men selected from the division of Leonatus.
At this point the narrative becomes strongly tinged with the usual exaggerations of the early navigators. Nearchus asserts that he observed strange phenomena in the heavens. When the sun was in the meridian, he says, no shadow was projected, and the stars which they were accustomed to see above them were now crouching close to the horizon; others, that had never before disappeared from the sky, now rose and set at intervals. The assertion in regard to shadows at noon is evidently a fabrication. Enough was known of astronomy and the motions of the heavenly bodies, in the time of Nearchus, to convince the learned that there must be a point where no shadow would be cast by a body directly beneath the sun at the summer solstice; and Nearchus, with a vanity quite usual in the conquerors and adventurers of those times, chose to assert, and he perhaps believed, that he had seen this singular phenomenon. Two circumstances will show the inaccuracy of his statement. The alleged appearance took place in the middle of the month of November, and twenty-five degrees north of the equator. Even had Nearchus been at this spot in midsummer, he would have seen shadows of very respectable length. Upon the coast of Gedrosia he found a people called Icthyophagi, or Fish-eaters. The mutton here tasted of fish, and Nearchus discovered that the sheep eat fish as well as the inhabitants, for the land yielded no pasturage.
In one of the villages of the Fish-eaters Nearchus engaged a pilot who undertook to guide him as far as Caramania. The aspect of the coast now became less repulsive, and palm-trees, myrtles, and flowers grew wild upon the hill-sides. Such was the delight of the Macedonians at this sight, that they landed and wove garlands and wreaths of the foliage for the wives and daughters of the natives. Farther on, at a spot where the inhabitants made them presents of roasted tunny-fish—the first cooked fish they had yet received from the Icthyophagi—and where they noticed wheat-fields, they landed, and, after taking possession of the village, demanded the surrender of all their wheat. The people made a feeble resistance, and then gave up all the flour they possessed,—not wheat flour, but fish flour,—flour made by reducing fish to powder, as we make flour by pulverizing the kernels of wheat.
