De casibus is an encyclopedia of historical biography and a part of the classical tradition of
historiography. It deals with the fortunes and calamities of famous people starting with the biblical Adam, going to mythological and ancient people, then to people of Boccaccio's own time in the fourteenth century. The work was so successful it spawned what has been referred to as the
De casibus tradition, influencing many other famous authors such as
Geoffrey Chaucer,
John Lydgate, and
Laurent de Premierfait. De casibus also inspired character figures in works like
The Canterbury Tales, ''
The Monk's Tale, the Fall of Princes
(c. 1438), Des cas de nobles hommes et femmes
(c. 1409), and Caida de principles
(a fifteenth-century Spanish collection), and A Mirror for Magistrates'' (a very popular sixteenth-century continuation written by
William Baldwin and others). ==Development==
