But because Alba was thus brought to destruction, Rome increased greatly; for the number of the citizens was increased twofold. The Cœlian hill was added to the city, in which hill, that others might the more readily dwell there, the king himself commanded that they should build him a palace. Also the chief houses of Alba, as the house of Julius and of Servilius, were chosen into the Senate; and that there might be a place of meeting for the Senate being thus multiplied, the king built a temple and called it Hostilia, after his own name. Also ten squadrons of horsemen were chosen out of the men of Alba. Now the end of King Tullus was this. There came a pestilence upon the land. And when for this cause the people were wearied of war, nevertheless the king, both because he delighted in war, and because he believed that the young men should have better health if they went abroad than if they tarried at home, gave them no rest. But after a while he also fell into a tedious sickness, which so brake him both in body and mind that, whereas in time past he thought it unworthy of a king to busy himself with matters of religion, now he gave himself up wholly to superstition, and filled the minds of his people also with the like thoughts, so that they regarded nothing but this, how they should make atonement to the gods, and so be rid of their present distress. As for the king himself, men say that reading the sacred book of King Numa he found therein certain sacrifices, very secret and solemn, that should be done to Jupiter by such as would bring him down from heaven, and that he shut himself up to do these sacrifices; but because he set not about them rightly or did than not in due form, there appeared to him no similitude of the immortal gods (for such he had hoped to see); but Jupiter, having great wrath at such unlawful dealings, struck him with lightning and consumed both him and his house.
