It was chiefly in the more showy departments of literature that the extravagance of the Marinists was most conspicuous, and the decay of native genius was most apparent. But this genius had turned into other paths, which it pursued with a steady, though less brilliant course. Of all branches of prose composition, the epistolary was the most carefully cultivated. The talent for letter-writing was often the means of considerable emolument, as all the petty princes of Italy and the cardinals of Rome were ambitious of having secretaries who would give them _éclat_ in their correspondence, and these situations, which were steps to higher preferment, were eagerly sought; hence the prodigious number of collections of letters which have at all times inundated Italy--specimens by which those who believed themselves elegant writers endeavored to make known their talent. The letters of Bentivoglio have obtained European celebrity. They are distinguished for elegance of style as well as for the interest of those historical recollections which they transmit; they are considered superior to his history. But of all the letters of this or of the preceding age, none are more rich, more varied, or more pleasing than those of Redi, who threw into this form his discoveries in natural history. The driest subjects, even those of language and grammar, are here treated in an interesting and agreeable manner. PERIOD THIRD.
