The rebuilding of the new city of Florence was begun by the Romans, as aforesaid, on a small site and circuit, after the same fashion as Rome, allowing for the smallness of the undertaking; and it began on the side of the sunrise at the gate of S. Piero, which was where were after the houses of M. Bellincione Berti, of the Rovignani, a noble and powerful citizen, albeit to-day they have disappeared; the which houses by inheritance of the Countess Gualdrada, his daughter, and wife to the first Count Guido, passed to the Counts Guidi, her descendants, when they became citizens of Florence, and afterwards they sold them to the Black Cerchi, a Florentine family; and from the said gate ran a borgo as far as S. Piero Maggiore, after the fashion of Rome, and from that gate the walls proceeded as far as the Duomo, on the site where now runs the great road leading to San Giovanni, as far as the Bishop's Palace. And here was another gate, which was called the gate of the Duomo, but there were who called it the Bishop's Gate; and without this gate was built the church of S. Lorenzo, just as in Rome there is S. Lorenzo without the walls; and within that gate is S. Giovanni, like as in Rome, S. Giovanni Laterano. And then proceeding, as at Rome, on that side they made Santa Maria Maggiore; and then from S. Michele Berteldi, as far as the third gate of S. Brancazio [S. Pancras], where are now the houses of the Tornaquinci, and S. Brancazio was without the city and near S. Paolo, just as in Rome, on the other side of the city over against S. Piero, as at Rome. And then from the said gate of S. Brancazio, they followed on where now is the church of Santa Trinita, which was without the walls; and hard by was a postern gate called the Porta Rossa, and down to our own times the road has retained the name. And afterward the walls turned where are now the houses of the Scali along the Via di Terma as far as the gate of Santa Maria, some way past the Mercato Nuovo, and that was the fourth principal gate, the which was over against the houses which now pertain to the Infangati, on one side; and above the said gate was the church of Santa Maria, called Sopra Porta; and afterwards when the said gate was pulled down, the city having increased, the said church was transported to where it now is. And the Borgo di Santo Apostolo was without the city, and also S. Stefano, after the fashion of Rome; and beyond S. Stefano, at the end of the master street of Porta Santa Maria, they made and built a bridge founded on piles of stone in the Arno, which afterwards was called the Ponte Vecchio, and it exists to this day; and was much more narrow than it now is, and was the first bridge which was made in Florence. And from S. Mary's Gate the walls went on as far as the turret of Altafonte, which was at the extremity of a projection of the city, running out to the river Arno, then running on behind the church of S. Piero Scheraggio, which was so called from a ditch or conduit
