It is now time to record the pursuits and the maxims of an academy, which, besides educating many illustrious pupils, perfected the art of their masters; and confirmed the axiom, that the shortest method of learning much is that of teaching. The three brothers were on the most perfect understanding as to the art of teaching, as free from venality as from envy; but the most laborious branches of the professorship were sustained by Agostino. He had drawn up a short treatise of perspective and architecture, from which he expounded to the school. He explained the nature of the bones and muscles, designating them by their names, in which he was assisted by Lanzoni the anatomist, who also secretly provided the school with bodies for such dissections as were required. His lectures were sometimes founded upon history, at others upon fictions; and these he illustrated, and offered for designs, which being exhibited at stated intervals, were examined by skilful judges, who decided upon their respective merits; as we gather from a ticket written to Cesi, one of the arbiters. The meed of fame was sufficient for the crowned candidates, round whom the poets collected to celebrate their name; with whom Agostino enthusiastically joined both with harp and voice, applauding the progress of his scholars. These last were likewise instructed in true criticism, and to give due praise or blame to the works of others; they were also taught to criticise their own works, and whoever could not give good reasons for what he had done, and defend his own work, must cancel it upon the spot. Each, however, was at liberty to pursue what path he pleased, or rather each entered upon that to which nature had best adapted him, which gave rise to so many original manners from the same studio; yet each style was to be founded upon reason, nature, and imitation. In all more doubtful points, recourse was had to the opinion of Lodovico; the cousins presided over the daily exercises of design, full of assiduity, industry, and perseverance. Even the recreations of the academicians had a view to art; to draw landscapes from nature, or to sketch caricatures, were the customary amusements of Annibale and the disciples of the school, when they wished to relax from study.[23]
