“ The Fiammetta is to the Decameron what rhetoric is to the drama. This, however, is hardly a deduction from its merit. The delineation of an unholy and unhappy passion, blessed with fruition for one brief moment, cursed through months of illness and despair with all the furies of vain desire and poignant recollection, is executed with incomparable fullness of detail and inexhaustible richness of fancy. The reader rises from a perusal of the Fiammetta with impressions similar to those which a work of Richardson leaves upon the mind. ”
