Query: Along with Dante and Boccaccio, who was a notable Italian author of the 14th century?
Context: The publication of vernacular literature increased, with Dante (d. 1321), Petrarch (d. 1374) and Giovanni Boccaccio (d. 1375) in 14th-century Italy, Geoffrey Chaucer (d. 1400) and William Langland (d. c. 1386) in England, and François Villon (d. 1464) and Christine de Pizan (d. c. 1430) in France. Much literature remained religious in character, and although a great deal of it continued to be written in Latin, a new demand developed for saints' lives and other devotional tracts in the vernacular languages.
