"Whenever, most gracious ladies, I reflect how pitiful you all are by nature, I recognize that this work will in your opinion have a sad and repulsive beginning, as the painful memory of the pestilence gone by, fraught with loss to all who saw or knew of it, and which memory the work will bear on its front. But I would not that for this you read no further, through fear that your reading should be always through sighs and tears. This frightful beginning I prepare for you as for travelers a rough and steep mountain, beyond which lies a most beautiful and delightful plain, by so much the more pleasurable as the difficulty of the ascent and passage of the mountain had been great. And as the extreme of pleasure touches pain, so suffering is effaced by a joy succeeding. To this brief vexation (I call it brief, as contained in few words) follow closely the sweets and pleasures I have promised, and which would not be hoped for from such a beginning if it were not foretold. And to tell the truth, if I had been able frankly to bring you where I wished by other way than this rough one, I had willingly done so; but because I could not, without these recollections, show what was the occasion of the incidents of which you will read, I was obliged to write of them."
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.
