1. HISTORICAL DEVELOPMENT OF THE THIRD PERIOD.--At the close of the seventeenth century, a new dawn arose in the history of Italian letters, and the general corruption which had extended to every branch of literature and paralyzed the Italian mind began to be arrested by the appearance of writers of better taste; the affectations of the Marinists and of the so-called Arcadian poets were banished from literature; science was elevated and its dominion extended, the melodrama, comedy, and tragedy recreated, and a new spirit infused into every branch of composition. Amidst the clash of arms and the vicissitudes of long and bloody wars, Italy began to awake from her lethargy to the aspiration for greater and better things, and her intellectual condition soon underwent important changes and improvements. In the eighteenth century, in Naples, Vico transformed history into a new science. Filangeri contended with Montesquieu for the palm of legislative philosophy; and new light was thrown on criminal science by Mario Pagano. In Rome, letters and science flourished under the patronage of Benedict XIV., Clement XIV., and Pius VI., under whose auspices Quirico Visconti undertook his "Pio Clementine Museum" and his "Greek and Roman Iconography," the two greatest archaeological works of all ages. Padua was immortalized by the works of Cesarotti, Belzoni, and Stratico; Venice by Goldoni; Verona by Maffei, the critic and the antiquarian, as well as the first reformer of Italian tragedy. Tuscany took the lead of the intellectual movement of the country under Leopold and his successor Ferdinand, when Florence, Pisa, and Siena again became seats of learning and of poetry and the arts. Maria Theresa and Joseph II. fostered the intellectual progress of Lombardy; Spallanzani published his researches on natural philosophy; Volta discovered the pile which bears his name; a new era in poetry was created by Parinl; another in criminal jurisprudence by Beccaria; history was reconstructed by Muratori; mathematics promoted by Lagrange, and astronomy by Oriani; and Alfieri restored Italian letters to their primitive splendor.
