When Sertorius had made himself absolute master of the whole country, he acted with great fairness to those who had confided in him, and who yielded to his mercy; he restored to them their property, cities, and government, accepting only of such acknowledgments as they themselves freely offered. And whilst he considered which way next to turn his arms, the Lusitanians sent ambassadors to desire him to be their general; for being terrified with the Roman power, and finding the necessity of having a commander of great authority and experience in war, being also sufficiently assured of his worth and valour by those who had formerly known him, they were desirous to commit themselves especially to his care. And in fact Sertorius is said to have been of a temper unassailable either by fear or pleasure, in adversity and dangers undaunted, and noways puffed up with prosperity. In straightforward fighting, no commander in his time was more bold and daring, and in whatever was to be performed in war by stratagem, secrecy, or surprise, if any strong place was to be secured, any pass to be gained speedily, for deceiving and overreaching an enemy, there was no man equal to him in subtlety and skill. In bestowing rewards and conferring honours upon those who had performed good service in the wars, he was bountiful and magnificent, and was no less sparing and moderate in inflicting punishment. It is true that that piece of harshness and cruelty which he executed in the latter part of his days upon the Spanish hostages seems to argue that his clemency was not natural to him, but only worn as a dress, and employed upon calculation, as his occasion or necessity required. As to my own opinion, I am persuaded that pure virtue, established by reason and judgment, can never be totally perverted or changed into its opposite, by any misfortune whatever. Yet I think it at the same time possible that virtuous inclinations and natural good qualities may, when unworthily oppressed by calamities, show, with change of fortune, some change and alteration of their temper; and thus I conceive it happened to Sertorius, who, when prosperity failed him, became exasperated by his disasters against those who had done him wrong.
The Lusitanians having sent for Sertorius, he left Africa, and being made general with absolute authority, he put all in order amongst them, and brought the neighbouring parts of Spain under subjection.
Most of the tribes voluntarily submitted themselves, won by the fame of his clemency and of his courage, and, to some extent, also, he availed himself of cunning artifices of his own devising to impose upon them and gain influence over them. Amongst which, certainly, that of the hind was not the least. Spanus, a countryman who lived in those parts, meeting by chance a hind that had recently calved, flying from the hunters, let the dam go, and pursuing the fawn, took it, being wonderfully pleased with the rarity of the colour, which was all milk-white. As at that time Sertorius was living in the neighbourhood, and accepted gladly any presents of fruit, fowl, or venison that the country afforded, and rewarded liberally those who presented them, the countryman brought him his young hind, which he took and was well pleased with at the first sight; but when in time he had made it so tame and gentle that it would come when he called, and follow him wheresoever he went, and could endure the noise and tumult of the camp, knowing well that uncivilized people are naturally prone to superstition, by little and little he raised it into something preternatural, saying that it was given him by the goddess Diana, and that it revealed to him many secrets. He added, also, further contrivances. If he had received at any time private intelligence that the enemies had made an incursion into any part of the districts under his command, or had solicited any city to revolt, he pretended that the hind had informed him of it in his sleep, and charged him to keep his forces in readiness. Or if again he had noticed that any of the commanders under him had got a victory, he would hide the messengers and bring forth the hind crowned with flowers, for joy of the good news that was to come, and would encourage them to rejoice and sacrifice to the gods for the good account they should soon receive of their prosperous success.
