After that the Fiesolans were come in great part to dwell in Florence, as aforesaid, the city multiplied in inhabitants and population; and as it increased in suburbs and dwellings, outside the small old city, after a little while it behoved of necessity that the city should increase its circuit, first with moats and palisades; and then in the time of Henry the Emperor they made the walls, to the end the suburbs and outgrowths, by reason of the wars which arose in Tuscany about the matter of the said Henry, might not be taken nor destroyed, and the city more readily besieged by its enemies. Wherefore, at that time, in the year of Christ 1078, as hereafter, in narrating the story of Henry III., shall be mentioned, the Florentines began the new walls, beginning from the east side at the gate of S. Piero Maggiore, the which was somewhat behind the church so called, enclosing the suburb of S. Piero Maggiore and the said church within the new walls, and afterwards, drawing them nearer in on the north side, a little distance from the said suburb, they made an angle at a postern which was called the Albertinelli Gate from a family which dwelt in that place, which was so called; then they drew them on as far as the gate of the Borgo S. Lorenzo [suburb of S. Lawrence] enclosing the said church within the walls; and after this were two posterns, one at the forked way of the Campo Corbolini, and the other the one afterwards called the Porta del Baschiera. Then they ran on as far as the Porta S. Paolo, and then continued as far as the Carraia Gate, where the wall ended, by the Arno; and there afterwards they began and built a bridge which is called the Carraia Bridge from the name of that gate; and then the walls continuing, not however very high, along the bank of the Arno, included what had been without the old walls, to wit the suburb of San Brancazio [S. Pancras], and that of Parione, and that of Santo Apostolo, and of the Porte Sante Marie as far as the Ponte Vecchio; and then afterwards along the bank of Arno as far as the fortress of Altafonte. From this point the walls withdrew somewhat from the bank of Arno, so that there remained a road between, and two postern gates whereby to come at the river; then they went on the same, and took a turn where now are the supports of the Rubaconte Bridge, and there at the turn was a gate called the Oxen Gate, because there without was held the cattle market, and afterwards it was named the gate of Master Ruggieri da Quona, forasmuch as the family of da Quona, when they came to dwell in the city, established themselves near the said gate. Then the walls went on behind S. Jacopo tra le Fosse (so called because it stood on fosses), as far as where to-day is the end of the piazza before the church of the Minor Friars called Santa Croce; and there was a postern which led to the island of Arno; then the walls went on in a straight line without any gate or postern, returning to S. Piero Maggiore whence they began.
