After this they returned to Siena, and in the year 1338, with their direction and design, there was made the new Church of S. Maria, near the Duomo Vecchio, towards Piazza Manetti; and no long time after, the people of Siena, remaining much satisfied with all the works that these men were making, determined with an occasion so apt to put into effect that which had been discussed many times, but up to then in vain--namely, the making of a public fountain on the principal square, opposite the Palagio della Signoria. Wherefore, this being entrusted to Agostino and Agnolo, they brought the waters of that fountain through pipes of lead and of clay, which was very difficult, and it began to play in the year 1343, on the first day of June, with much pleasure and contentment to the whole city, which remained thereby much indebted to the talent of these its two citizens. About the same time there was made the Great Council Chamber in the Municipal Palace; and so too, with the direction and design of the same men, there was brought to its completion the tower of the said Palace, in the year 1344, and there were placed thereon two great bells, whereof they had one from Grosseto and the other was made in Siena. Finally, while Agnolo chanced to be in the city of Assisi, where he made a chapel and a tomb in marble in the lower Church of S. Francesco for a brother of Napoleone Orsino, a Cardinal and a friar of S. Francis, who had died in that place--Agostino, who had remained in Siena in the service of the State, died while he was busy making the design for the adornments of the said fountain in the square, and was honourably buried in the Duomo. I have not yet found, and cannot therefore say anything about the matter, either how or when Agnolo died, or even any other works of importance by their hand; and therefore let this be the end of their Life. Now, seeing that it would be without doubt an error, in following the order of time, not to make mention of some who, although they have not wrought so many works that it is possible to write their whole life, have none the less contributed betterment and beauty to art and to the world, I will say, taking occasion from that which has been said above about the Vescovado of Arezzo and about the Pieve, that Pietro and Paolo, goldsmiths of Arezzo, who learnt design from Agnolo and Agostino of Siena, were the first who wrought large works of some excellence with the chasing-tool, since, for an arch-priest of the said Pieve of Arezzo, they executed a head in silver as large as life, wherein was placed the head of S. Donatus, Bishop and Protector of that city; which work was worthy of nothing but praise, both because they made therein some very beautiful figures in enamel and other ornaments, and because it was one of the first works, as it has been said, that were wrought with the chasing-tool.
