he introduced a great number of figures and spared no pains, it has been praised even to our own day by those whose judgment does not extend beyond such circumstances.
Among other children Niccola had a son called Giovanni, who was always with his father, and under his care learned both sculpture and architecture, so that in the course of a few years he became not only the equal of his father, but his superior in some things. Thus, as Niccola was already old, he withdrew to Pisa and lived quietly there, leaving the control of everything to his son. At the death in Perugia of Pope Urban IV., Giovanni was sent for to make the tomb, which he executed in marble; but it was afterwards thrown down, together with that of Pope Martin IV., when the Perugians enlarged their Vescovado, so that only a few remains may be seen to-day dispersed about the church. At the same time the Perugians, thanks to the skill and industry of a friar of the Silvestrini, had brought to their city from the hill of Pacciano, two miles away, an abundance of water. The ornamentation of the fountain in both bronze and marble was entrusted to Giovanni, so that he thereupon set his hand to the work, making three basins, one above the other, two in marble and one in bronze. The first is placed at the top of a flight of steps of twelve faces, the second rests on some pillars which rise from the centre of the first, while the third, which is of bronze, is supported by three figures; and in the middle are griffins, also of bronze, which throw out water on every side. And as Giovanni considered that he had executed an excellent piece of work, he put his name to it. The arches and conduits of this fountain, which cost 160,000 gold ducats, were found to be very much worn and broken about the year 1560, but Vincenzio Danti, sculptor of Perugia, contrived a means, to his great glory, of bringing water to the fountain in the original way, without rebuilding the arches, which would have been very costly. When the work was finished Giovanni felt anxious to return to see his old father, who was sick, and he set out from Perugia intending to return to Pisa; but on his way through Florence he was compelled to stay there, to assist with others at the mills of the Arno, which were being made at S. Gregorio, near the piazza dei Mozzi. But at length receiving word that his father Niccola was dead, he departed for Pisa, where he was received with great honour by all the city, on account of his worth, since everyone rejoiced that although Niccola was lost to them, yet they still possessed Giovanni, who inherited his father's ability as well as his property. Nor were they deceived in him when the time of testing arrived, for when it was necessary to do some few things for the tiny but highly-ornate church of S. Maria della Spina, the task was entrusted to Giovanni. He therefore put his hand to the work and brought the ornamentation of that oratory to the state of perfection which it possesses to-day, the more so as he introduced the portrait of Niccola, taken from life, executed to the best of his ability. When the Pisans had seen this they decided to entrust him the construction of the Campo Santo, which is against the piazza del Duomo towards the walls, as they had long desired and talked of having a place for the burial of all their dead, both gentle and simple, so that the Duomo should not be filled with tombs, or for other reasons. Thus Giovanni with good designs and great judgment erected the building as we now see it, in style, size, and marble ornamentation, and as no expense was spared, it was roofed with lead. On the outside of the principle entrance may be read these words, carved in the marble:
