Tommaso Laureti, a Sicilian, already noticed with commendation by us among the scholars of F. Sebastiano, and deserving honourable mention among the professors of Bologna, was invited to Rome in the pontificate of Gregory XIII., and was entrusted with a work of an invidious nature. This was the decoration of the ceiling and lunettes in the Hall of Constantine, the lower part of which had been illustrated by the pencils of Giulio Romano and Perino. The subjects chosen by this master were intended to commemorate the piety of Constantine, idols subverted, the cross exalted, and provinces added to the church. Baglione informs us that Laureti was entertained by the Pope in his palace in a princely manner; and either from his natural indolence, or his reluctance to return to a laborious profession, procrastinated the work so much, that Gregory died, and Sixtus commenced his reign before it was completed. The new pontiff was aware that the artist had abused the patience of his predecessor, and became so exasperated, that Laureti, in order to avert his wrath, proceeded in all haste to finish his labours. When the work however was exposed to public view, in the first year of the new pontificate, it was judged unworthy of the situation. The figures were too vast and heavy, the colouring crude, the forms vulgar. The best part of it was a temple in the ceiling, drawn in excellent perspective, in which art indeed Laureti may be considered as one of the first masters of his day. Misfortune was added to his disgrace; for he was not only not rewarded as he had expected, but the cost of his living and provisions were placed to his charge, even to the corn supplied to his horse. So that he gained no remuneration, and actually died in poverty in the succeeding pontificate. He had however an opportunity afforded him of redeeming his credit, particularly in the stories of Brutus and Horatius on the bridge, which he painted in the Campidoglio, in a much better style. Intimately acquainted with the theory of art, and possessing an agreeable manner of inculcating its principles, he taught at Rome with considerable applause. He had a scholar and assistant in the Vatican, in Antonio Scalvati, a Bolognese, who in the time of Sixtus was employed among the painters of the Library, and who was afterwards engaged in painting portraits under Clement VIII., Leo XI., and Paul V.; and was highly celebrated in this department.
