Monreale, for the Emperor Frederick and by order of Manfred, he died, leaving Arnolfo, his son, heir no less to the talent than to the wealth of his father. This Arnolfo, from whose talent architecture gained no less betterment than painting had gained from that of Cimabue, being born in the year 1232, was thirty years of age when his father died, and was held in very great esteem, for the reason that, having not only learnt from his father all that he knew, but having also given attention under Cimabue to design in order to make use of it in sculpture, he was held by so much the best architect in Tuscany, that not only did the Florentines found the last circle of the walls of their city under his direction, in the year 1284, and make after his design the Loggia and the piers of Or San Michele, where the grain was sold, building them of bricks and with a simple roof above, but by his counsel, in the same year when the Poggio de' Magnuoli collapsed, on the brow of S. Giorgio above S. Lucia in the Via de' Bardi, they determined by means of a public decree that there should be no more building on the said spot, nor should any edifice be ever made, seeing that by the sinking of the stones, which have water trickling under them, there would be always danger in whatsoever edifice might be made there. That this is true has been seen in our own day from the ruin of many buildings and magnificent houses of noblemen. In the next year, 1285, he founded the Loggia and Piazza de' Priori, and built the principal chapel of the Badia of Florence, and the two that are on either side of it, renovating the church and the choir, which at first had been made much smaller by Count Ugo, founder of that abbey; and for Cardinal Giovanni degli Orsini, Legate of the Pope in Tuscany, he built the campanile of the said church, which, according to the works of those times, was much praised, although it did not have its completion of grey-stone until afterwards, in the year 1330.
