The Decameron is a collection of novellas by the 14th-century Italian author Giovanni Boccaccio (1313-1375). The book is structured as a frame story containing 100 tales told by a group of seven young women and three young men; they shelter in a secluded villa just outside Florence in order to escape the Black Death, which was afflicting the city. Boccaccio probably conceived of The Decameron after the epidemic of 1348, and completed it by 1353. Tales of love, wit, practical jokes, and life lessons contribute to the mosaic. In addition to its literary value and widespread influence (for example on Chaucer's Canterbury Tales), it provides a document of life at the time. Written in the vernacular of the Florentine language, it is considered a masterpiece of classical early Italian prose.
