His most esteemed works in fresco, for which he was honoured with the title of cavaliere, were exhibited in the palace called del Giardino, at Parma. His labours in the Cupola of S. Abbondio, before-mentioned, were on a magnificent scale, though designed from Giulio Campi. But they display a mastery of hand, and strength of colouring, fully equal, if not superior, to the invention of the work. For Giulio, indeed, did not possess the same skill in varying his groups of angels as the Caracci; inasmuch as both he and his family were accustomed to arrange them like the horses we see in the ancient chariots, all drawn up in a line, or in some other manner unusual in the best schools. The Cremonese historian endeavours, in some degree, to defend Trotti from the charge of harshness, casting it upon his assistants and disciples, whose altar-pieces have been attributed to Malosso, by Baldinucci. This may be the case with some, but there are others inscribed with the name of Trotti, especially at Piacenza, which more or less exhibit the same fault. Nor ought we to cast reflections upon an artist of a secondary character, on account of some errors, as these are precisely the cause of his exclusion from the rank of the very first masters. Trotti educated a number of artists who flourished about the year 1600, devoted to his manner, although in course of time the method of preparing grounds becoming corrupted throughout Italy, and the age attached to a more sombre style of colouring, they were induced to abandon much of that clearness which forms a chief characteristic of his colouring. Baldinucci gives some account of Ermenegildo Lodi, as well as Orlandi, who could not discern which of two paintings belonged to the master, and which to the scholar. This, I conjecture, arose from painting under the eye of his preceptor, whom he assisted in many of his labours, together with his brother Manfredo Lodi. When we consult the few which he executed alone, particularly at S. Pietro, they discover nothing to have excited the jealousy of Agostino Caracci, nor to have gained for the artist the appellation of Malosso. The productions likewise of Giulio Calvi, called Il Coronaro, might be mistaken for the least perfect of those of Trotti, says Zaist, where they are not inscribed with his name. The same may be averred of two other artists, Stefano Lambri and Cristoforo Augusta, a youth of great promise, cut off in the flower of his age; and both excellent disciples of the school. These, no less than Coronaro, may be seen and compared with each other in the church and convent of the Padri Predicatori, which possess specimens of each.
