Next, having returned to Florence, Taddeo continued for the Commune the work of Orsanmichele and refounded the piers of the Loggia, building them with stone dressed and well shaped, whereas before they had been made of bricks, without, however, altering the design that Arnolfo left, with directions that there should be made over the Loggia a palace with two vaults for storing the provisions of grain that the people and Commune of Florence used to make. To the end that this work might be finished, the Guild of Porta S. Maria, to which the charge of the fabric had been given, ordained that there should be paid thereunto the tax of the square of the grain-market and some other taxes of very small importance. But what was far more important, it was well ordained with the best counsel that each of the Guilds of Florence should make one pier by itself, with the Patron Saint of the Guild in a niche therein, and that every year, on the festival of each Saint the Consuls of that Guild should go to church to make offering, and should hold there the whole of that day the standard with their insignia, but that the offering, none the less, should be to the Madonna for the succour of the needy poor. And because, during the great flood of the year 1333, the waters had swept away the parapets of the Ponte Rubaconte, thrown down the Castle of Altafronte, left nothing of the Ponte Vecchio but the two piers in the middle, and completely ruined the Ponte a S. Trinita except one pier that remained all shattered, as well as half the Ponte alla Carraia, bursting also the weir of Ognissanti, those who then ruled the city determined no longer to allow the dwellers on the other side of the Arno to have to return to their homes with so great inconvenience as was caused by their having to cross in boats. Wherefore, having sent for Taddeo Gaddi, for the reason that Giotto his master had gone to Milan, they caused him to make the model and design of the Ponte Vecchio, giving him instructions that he should have it brought to completion as strong and as beautiful as might be possible; and he, sparing neither cost nor labour, made it with such strength in the piers and with such magnificence in the arches, all of stone squared with the chisel, that it supports to-day twenty-two shops on either side, which make in all forty-four, with great profit to the Commune, which drew from them eight hundred florins yearly in rents. The extent of the arches from one side to the other is thirty-two braccia, that of the street in the middle is sixteen braccia, and that of the shops on either side eight braccia. For this work, which cost sixty thousand florins of gold, not only did Taddeo then deserve infinite praise, but even to-day he is more than ever commended for it, for the reason that, besides many other floods, it was not moved in the year 1557, on September 13, by that which threw down the Ponte a S. Trinita and two arches of that of the Carraia, and
