The Decameron
Boccaccio began work on "The Decameron" around 1349. It is probable that the structures of many of the tales date from earlier in his career, but the choice of a hundred tales and the frame-story "lieta brigata" of three men and seven women dates from this time. The work was largely complete by 1352. It was Boccaccio's final effort in literature and one of his last works in Tuscan vernacular; the only other substantial work was "Corbaccio" (dated to either 1355 or 1365). Boccaccio revised and rewrote "The Decameron" in 1370–1371. This manuscript has survived to the present day.
