XLIII. Trajan to Pliny
YOU are of opinion it would be proper to establish a company of firemen in Nicomedia, agreeably to what has been practised in several other cities. But it is to be remembered that societies of this sort have greatly disturbed the peace of the province in general, and of those cities in particular. Whatever name we give them, and for whatever purposes them may be founded, they will not fail to form themselves into factious, assemblies, however short their meetings may be. It will therefore be safer to provide such machines as are of service in extinguishing fires, enjoining the owners of houses to assist in preventing the mischief from spreading, and, if it should be necessary, to call in the aid of the populace.
