Through the above-mentioned gate, which is at the upper end of this garden, above some steps, one enters into another garden, as wide as the first, but of no great depth in the direct line, in comparison with the mountain beyond. In this garden were to be two other loggie, one on either side, and in the wall opposite to the gate, which supports the soil of the mountain, there was to be in the centre a grotto with three basins, with water playing into them in imitation of rain. The grotto was to be between two fountains placed in the same wall, and opposite to these, in the lower wall of the garden, were to be two others, one on either side of the gate; so that the fountains of this garden would have been equal in number to those of the other, which is below it, and receives its water from the first, which is higher. And this garden was to be all full of orange-trees, which would have had--and will have, whenever that may be--a most favourable situation, being defended by the walls and by the mountain from the north wind and other harmful winds. From this garden one climbs by two staircases of flint, one on either side, to a forest of cypresses, fir-trees, holm-oaks, laurels, and other evergreen trees, distributed with beautiful order, in the middle of which, according to Tribolo's design, there was to be a most lovely fish-pond, which has since been made. And because this part, gradually narrowing, forms an angle, that angle, to the end that it might be made flat, was to be blunted by the breadth of a loggia, from which, after climbing some steps, might be seen in front the palace, the gardens, the fountains, and all the plain below and about them, as far as the Ducal Villa of Poggio a Caiano, Florence, Prato, Siena, and all that is around for many miles. Now the above-named Maestro Pietro da San Casciano, having carried his work of the aqueduct as far as Castello, and having turned into it all the waters of Castellina, was overtaken by a violent fever, and died in a few days. Whereupon Tribolo, undertaking the charge of directing all the building by himself, perceived that, although the waters brought to Castello were in great abundance, nevertheless they were not sufficient for all that he had made up his mind to do; not to mention that, coming from Castellina, they did not rise to the height that he required for his purposes. Having therefore obtained from the Lord Duke a commission to conduct thither the waters of Petraia, a place more than one hundred and fifty braccia above Castello, which are good and very abundant, he caused a conduit to be made, similar to the other, and so high that one can enter into it, to the end that thus those waters of Petraia might come to the fish-pond through another aqueduct with enough fall for the fish-pond and the great fountain.
