"Petrarch, a character on whom I never think but with love, formed his mind entirely in Solitude, and there rendered himself capable of transacting the most important political affairs. Petrarch was, doubtless, sometimes what persons frequently become in Solitude, satirical, peevish and choleric. He has, in particular, been reproached with great severities, on account of his lively pictures of the manners of his age, and especially his description of the infamous vices practised at Avignon, during the pontificate of the sixth Clement. But Petrarch possessed a profound knowledge of the human heart, and extraordinary address in working upon the passions and directing them as he pleased. The Abbé de Sade, the best historian of his life, says, that he is scarcely known, but as the tender and elegant poet, who loved with ardor and sung in the most impassioned strains the charms of his mistress; and that nothing more is known of his character. Even authors are ignorant of the obligations which literature owes him; that he rescued it from the barbarism beneath which it had so long been buried; that he saved the best works of the ancient writers from dust and destruction, and that all these treasures would have been lost to us, if he had not sought and procured correct copies of them."
