Suetonius Nero 16

He devised a new style of building in the city, ordering piazzas to be erected before all houses both in the streets and detached, to give facilities from their terraces, in case of fire, for preventing it from spreading; and these he built at his own expense. He likewise designed to extend the city walls as far as Ostia , and bring the sea from thence by a canal into the old city. Many severe regulations and new orders were made in his time. A sumptuary law was enacted. Public suppers were limited to the Sportulae; ¹ and victualling-houses restrained from selling any dressed victuals, except pulse and herbs, whereas before they sold all kinds of meat. He likewise inflicted punishments on the Christians, a sort of people who held a new and impious ² superstition. He forbad the revels of the charioteers, who had long assumed a licence to stroll about, and established for themselves a kind of prescriptive right to cheat and thieve, making a jest of it. The partisans of the rival theatrical performers were banished, as well as the actors themselves.
