Where the Bibieni had failed in introducing their novel inventions for grand spectacles, their disciples finally succeeded. In this list, according to the history of Zanotti and of Crespi, the most eminent rank is held by Domenico Francia, once the assistant of Ferdinando at Vienna, afterwards architect and painter to the King of Sweden. After his term with that court had elapsed, he visited Portugal, and again proceeded to Italy and Germany, till his arrival in his native place, where he died. To him we may add the name of Vittorio Bigari, mentioned in high terms by Zanotti, an artist employed by different sovereigns of Europe, and the father of three sons, who pursued the same career. He also displayed singular merit in his figures. Nor must we omit Serafino Brizzi, who obtained equal reputation for his perspectives in oil interspersed both throughout foreign and native cities. It would form, however, an undertaking no way adapted to a compendious history, to collect the names of all the professors of so extended an art; and the more so as, in the course of the present age, it was becoming the general opinion that in many respects such art was greatly on the decline, owing to the prevalence of only middling and inferior artificers. Not many years ago, however, it seemed to revive, and a new epoch opened upon the public, the praise of which is due to Mauro Tesi, to whom his friends raised a marble monument in S. Petronio, with a bust and the following inscription: "Mauro Tesi elegantiæ veteris in pingendo ornatu et architectura restitutori." He belonged to the state of Modena, and, when young, was put to the school of a very poor painter of arms in Bologna. Thus it was his lot, writes Algarotti, to have had not a single master of architecture among the moderns. By means of a peculiar natural genius, and studying the designs of Mitelli and Colonna, examining at the same time their models throughout the city, he re-conducted the art to a style, solid in architecture, sparing in decoration, as it had formerly been, and in some parts still more philosophical and learned. His patron, the excellent Count Algarotti, assisted in perfecting his taste, and made him his companion on his tours, encouraging him to make very excellent observations on the works of the ancients. Whoever has perused his life and publications, a fine edition of which appeared at Venice, edited by the learned Aglietti, will have perceived that he was as much attached to Tesi as if he had been his own son. Nor did Tesi shew less respect to Algarotti than to a father; and when the latter went to Pisa for his health, his young friend devoted himself so assiduously to him, as to contract the same disease, of which he died two years afterwards, still very young, at Bologna. Here he left various works, the most conspicuous consisting of a gallery belonging to the deceased Marquis Zambeccari, with marbles, camei,
