who on account of their prodigiously long lives are called Macrobiotae; for, because they did not receive slavery with hands uplifted to heaven in thankfulness, and sent an embassy which used independent, or what kings call insulting language, Cambyses became wild with rage, and, without any store of provisions, or any knowledge of the roads, started with all his fighting men through an arid and trackless waste, where during the first day’s march the necessaries of life failed, and the country itself furnished nothing, being barren and uncultivated, and untrodden by the foot of man. At first the tenderest parts of leaves and shoots of trees relieved their hunger, then hides softened by fire, and anything else that their extremity drove them to use as food. When as they proceeded neither roots nor herbs were to be found in the sand, and they found a wilderness destitute even of animal life, they chose each tenth man by lot and made of him a meal which was more cruel than hunger. Rage still drove the king madly forwards, until after he had lost one part of his army and eaten another he began to fear that he also might be called upon to draw the lot for his life; then at last he gave the order for retreat.
