But the rest of the old site not occupied by his palace was laid out, not as after the Gallic fire without discrimination and regularity, but with the lines of streets measured out, broad spaces left for transit, the height of the buildings limited, open areas left, and porticoes added to protect the front of the clustered dwellings: these porticoes Nero engaged to rear at his own expense, and then to deliver to each proprietor the areas about them cleared. He, moreover, proposed rewards proportioned to every man's rank and private substance, and fixed a day within which, if their houses, single and clustered, were finished, they should receive them. He appointed the marshes of Ostia for a receptacle of the rubbish, and that the vessels which had conveyed grain up the Tiber should return laden with rubbish; that the buildings themselves should be raised a certain portion of their height without beams, and arched with stone from the quarries of Gabii or Alba, that stone being proof against fire; that over the water springs, which had been improperly intercepted by private individuals, overseers should be placed, to provide for their flowing in greater abundance, and in a greater number of places, for the supply of the public; that every housekeeper should have in his yard means for extinguishing fire, neither should there be party walls, but every house should be enclosed by its own walls.[28] These regulations, which were favorably received, in consideration of their utility, were also a source of beauty to the new city; yet some there were who believed that the ancient form was more conducive to health, as from the narrowness of the streets and the height of the buildings the rays of the sun were more excluded; whereas now, the spacious breadth of the streets, without any shade to protect it, was more intensely heated in warm weather. Such were the provisions made by human counsels. The gods were next addressed with expiations, and recourse had to the sibyl's books. By admonition from them to Vulcan, Ceres, and Proserpina, supplicatory sacrifices were made, and Juno propitiated by the matrons, first in the Capitol, then upon the nearest shore, where, by water drawn from the sea, the temple and image of the goddess were besprinkled; the ceremony of placing the goddess in her sacred chair, and her vigil, were celebrated by ladies who had husbands. But not all the relief that could come from man, not all the bounties that the prince could bestow, nor all the atonements which could be presented to the gods availed to relieve Nero from the infamy of being believed to have ordered the conflagration. Hence, to suppress the rumor, he falsely charged with the guilt and punished with the most exquisite tortures the persons commonly called Christians, who were hated for their enormities.
