This isolation from the rest of the world has brutalised their character, which even by nature is far from humane. They have long claw-like nails and long shaggy hair, for they cut the growth of neither. They live in huts constructed of shells and other offscourings of the sea. Their clothing consists of the skins of wild beasts, and they feed on fish dried in the sun, and on the flesh of sea monsters cast on the shore during stormy weather.[329] The Macedonians having by this time consumed all their provisions, suffered first from scarcity and at last from hunger, so that they were driven to search everywhere for the roots of the palm, which is the only tree that country produces. When even this kind of food failed them, they began to kill their beasts of burden, and did not spare even their horses. They were thus deprived of the means of carrying their baggage, and had to burn the rich spoils taken from their enemies, for the sake of which they had marched to the utmost extremities of the East. A pestilence succeeded the famine, for the new juices of the unwholesome esculents on which they fed, superadded to the fatigue of marching and the strain of their mental anxiety, had spread various distempers among them, so that they were threatened with destruction whether they remained where they were or resumed their march. If they stayed famine would assail them, and if they advanced a still deadlier enemy, pestilence, would have them in its grasp. The plains were in consequence bestrewn with almost more bodies of the dying than of the dead. Even those who suffered least from the distemper could not keep pace with the main army, because every one believed that the faster he travelled he advanced the more surely to health and safety. The men, therefore, whose strength failed craved help from all and sundry, whether known to them or unknown. But there were no beasts of burden now by which they could be taken on, and the soldiers had enough to do to carry their arms, whilst at the same time the dreadful figure of the calamity impending over themselves was ever before their eyes. Being thus repeatedly appealed to, they could not so much as bear to cast back a look at their comrades, their pity for others being lost in their fears for themselves.
