The elaborate description of the plague which follows, shows not only Boccaccio’s inventive power,—as being, like that of Defoe of the plague of London (which is a curious parallel to this) altogether imaginary, since the writer was at Naples during the whole period of the pestilence,—but also that it was a part indispensable of the entire scheme, and described with all its ghastly minuteness simply to enhance the value of his sunshine and merriment. He was in Naples from 1345 until 1350, without any other indication of a visit to Florence than a chronological table of his life, in which occurs this item:—“1348, departs in the direction of Tuscany with Louis of Taranto:” as if either a prince on his travels would take the plague in the course of them, or a man so closely interested in the events of the time at Naples, and in the height of his passion for Fiammetta,—the separation from whom he had hardly endured when earlier (1345) he was separated from her by his duty to his aged father,—would have chosen the year of the pestilence, when every one who could, fled Florence, to return there; and we find him in May, 1349, in Naples, in the full sunshine of Fiammetta’s favor, and remaining there until his father’s death in 1350.
There is indeed in Boccaccio’s description of the plague that which convicts it of pure invention, quickened by details gathered from eye-witnesses,—the very minuteness of the description in certain points not in accord with the character of the disease, as when he narrates that the hogs rooting in the garments of the dead thrown out into the streets “presently, as if they had taken poison, after a few dizzy turns, fell dead”; and this, which he says he saw with his own eyes, is the only incident of which he makes this declaration (the incident on which the unity of his work hinges, the meeting of the merry troupe in the church of S. Maria Novella, being recorded on the information of a person “worthy of belief"). Nor does he in his own person intrude anywhere in the story; so that this bit of intense realization thrown into the near foreground of his picture, as it were by chance, and without meaning, yet certified by his own signature, is the point at which he gets touch of his reader and convinces him of actuality throughout the romance.
