From Pselchis Petronius went to Premnis,[896] a strong city, travelling over the hills of sand, beneath which the army of Cambyses was overwhelmed by the setting in of a whirlwind. He took the fortress at the first onset, and afterwards advanced to Napata.[897] This was the royal seat of Candace; and her son was there, but she herself was in a neighbouring stronghold. When she sent ambassadors to treat of peace, and to offer the restitution of the prisoners brought from Syene, and the statues, Petronius attacked and took Napata, from which her son had fled, and then razed it. He made prisoners of the inhabitants, and returned back again with the booty, as he judged any farther advance into the country impracticable on account of the roads. He strengthened, however, the fortifications of Premnis, and having placed a garrison there, with two years’ provisions for four hundred men, returned to Alexandreia. Some of the prisoners were publicly sold as booty, and a thousand were sent to Cæsar, who had lately returned from the Cantabrians,[898] others died of various diseases. In the mean time Candace[899] attacked the garrison with an army of many thousand men. Petronius came to its assistance, and entering the fortress before the approach of the enemy, secured the place by many expedients. The enemy sent ambassadors, but he ordered them to repair to Cæsar: on their replying, that they did not know who Cæsar was, nor where they were to find him, Petronius appointed persons to conduct them to his presence. They arrived at Samos, where Cæsar was at that time, and from whence he was on the point of proceeding into Syria, having already despatched Tiberius into Armenia. The ambassadors obtained all that they desired, and Cæsar even remitted the tribute which he had imposed. CHAPTER II. 1. In the preceding part[900] of this work we have spoken at length of Ethiopia, so that its description may be said to be included in that of Egypt. In general, then, the extreme parts of the habitable world adjacent to the intemperate region, which is not habitable by reason either of heat or cold, must necessarily be defective and inferior, in respect to physical advantages, to the temperate [CAS. 821] region. This is evident from the mode of life of the inhabitants, and their want of what is requisite for the use and subsistence of man. For the mode of life [of the Ethiopians] is wretched; they are for the most part naked, and wander from place to place with their flocks. Their flocks and herds are small in size, whether sheep, goats, or oxen; the dogs also, though fierce and quarrelsome, are small.[901] It was perhaps from the diminutive size of these people, that the story of the Pygmies originated, whom no person, worthy of credit has asserted that he himself has seen.
