Another long list of names from the books, given between 1500 and 1550 by Merzario, proves that the Comacines still reigned supreme in the laborerium, the Solari family preponderating.

As if to connect the last link in the chain with the first, we find the old family of Bono da Campione still prominent. For nearly thirty years, i.e. between 1618 and 1647, Magister Gian Giacomo Bono da Campione sculptured in the laborerium of the Duomo, and there his son Francesco was trained, besides two kinsmen—Carlo Antonio Bono, painter and sculptor, and his son, Giuseppe. All this family worked together in the seventeenth century at the façade of the cathedral, designed by Pellegrini. The fine central door was the work of Gian Giacomo Bono and Andrea Castelli, both Comacines by birth.

As for the names of other Comacines who worked at the façade and on the wondrous roof, one finds them by hundreds in the annals of the Duomo, as collected by Giulini in his Memorie della Città e Campagna di Milano. Here you see names repeated which have been familiar in the guild for centuries; such as the Bono and Solari families, and Luca Beltrami, who worked at the façade in the seventeenth century, and whose ancestors were architects at Modena and Parma two hundred years earlier.

Whatever were the faults of Gian Galeazzo Visconti, the world has one great and beautiful legacy to thank him for—the Certosa of Pavia.

It is said that Stefano Maconi, prior of the Certosa at Garignano, suggested to the Duke the building of the finest monastery in Italy; but the funds were certainly provided by Gian Galeazzo, who took a personal and untiring interest in the work.

The first documental proof of this is a deed of gift, dated April 15, 1396, whereby Gian Galeazzo gives to the monastery of the Certosa, landed property to the annual value of 2500 gold florins. On October 6 of the same year, he makes another endowment of property, yielding 5500 gold florins a year, besides an annual subsidy of 10,000 florins from his own private purse.

The history of this beautiful building is much connected with that of Milan cathedral; the same architects—or rather brethren of the same Masonic Lodge—worked at both; and at one time Jacopo da Campione was capo maestro of both works at once, spending a certain proportion of his time at both.
