Then Macrinus, Albinus, Gneus Pompey, and Marcius, furnished with materials and workmen, came from Rome to the city which Caesar was building, and agreed with Caesar to divide the work after this manner: that Albinus undertook to pave all the city, which was a noble work and gave beauty and charm to the city, and to this day fragments of the work are found, in digging, especially in the sesto of Santo Piero Scheraggio, and in Porta San Piero, and in Porta del Duomo, where it shows that the ancient city was. Macrinus caused the water to be brought in conduits and aqueducts, bringing it from a distance of seven miles from the city, to the end the city might have abundance of good water to drink and to cleanse the city; and this conduit was carried from the river called Marina at the foot of Montemorello, gathering to itself all the springs above Sesto and Quinto and Colonnata. And in Florence the said springs came to a head at a great palace which was called "caput aquae," but afterwards in our speech it was called Capaccia, and the remains can be seen in the Terma until this day. And note that the ancients, for health's sake, used to drink spring waters brought in by conduits, forasmuch as they were purer and more wholesome than water from wells; seeing that few, indeed very few, drank wine, but the most part water from conduits, but not from wells; and as yet there were very few vines. Gneus Pompey caused the walls of the city to be built of burnt bricks, and upon the walls of the city he built many round towers, and the space between one tower and the other was twenty cubits, and it was so that the towers were of great beauty and strength. Concerning the size and circuit of the city we can find no chronicle which makes mention thereof; save that when Totila, the scourge of God, destroyed it, history records that it was very great. Marcius, the other Roman lord, caused the Capitol to be built after the fashion of Rome, that is to say the palace, or master fortress of the city, and this was of marvellous beauty; into which the water of the river Arno came by a hollowed and vaulted passage, and returned into the Arno underground; and the city, at every festival, was cleansed by the outpouring of this duct. This Capitol stood where to-day is the piazza which is called the Mercato Vecchio, over against the church which is called S. Maria, in Campidoglio. This seems to be the best supported opinion; but some say that it was where the place is now called the Guardingo [citadel]; beside the Piazza di Popolo (so called from the Priors' Palace), which was another fortress. Guardingo was the name afterwards given to the remains of the walls and arches after the destruction by Totila, where the bad quarter was. And the said lords each strove to be in advance of the work of the others. And at one same time the whole was completed, so that to none of them was the favour granted of naming the city
