In the Church of S. Agostino, in the chapel and on the altar of the Nardi, he painted in fresco some stories of S. Laurence, with marvellous manner and execution.
And because he exercised himself also in the things of architecture, by order of the sixty aforesaid citizens he reconducted under the walls of Arezzo the water that comes from the foot of the hill of Pori, three hundred braccia distant from the city. This water, in the time of the Romans, had been brought first to the theatre, whereof the remains are still there, and from that theatre, which was on the hill where to-day there is the fortress, to the amphitheatre of the same city, on the plain; but these edifices and conduits were wholly ruined and spoilt by the Goths. Jacopo, then, as it has been said, having brought this water below the walls, made the fountain which was then called the Fonte Guizianelli, and which is now named, by the corruption of the word, the Fonte Viniziana; this work endured from that time, which was the year 1354, up to the year 1527, and no more, for the reason that the plague of that year, the war that came afterwards, the fact that many intercepted the water at their own convenience for the use of their gardens, and still more the fact that Jacopo did not sink it, brought it about that to-day it is not, as it should be, standing.
The while that the aqueduct was going on being built, Jacopo, not leaving aside his painting, wrought many scenes from the acts of Bishop Guido and Piero Sacconi in the palace that was in the old citadel, now in ruins; for these men, both in peace and in war, had done great and honourable deeds for that city. In the Pieve, likewise, below the organ, he wrought the story of S. Matthew and many other works. And so, making works with his own hand throughout the whole city, he showed to Spinello Aretino the principles of that art which was taught to him by Agnolo, and which Spinello taught afterwards to Bernardo Daddi, who, working in his own city, honoured it with many beautiful works of painting, which, together with his other most noble qualities, brought it about that he was much honoured by his fellow-citizens, who employed him much in magistracies and in other public affairs. The paintings of Bernardo were many and in much esteem, and above all the Chapel of S. Lorenzo and of S. Stefano, belonging to the Pulci and Berardi, in S. Croce, and many other paintings in diverse places in the said church. Finally, having made some pictures over the gates of the city of Florence on the inner side, he died, laden with years, and was given honourable burial in S. Felicita, in the year 1380.
