Giovanni Boccaccio (/boʊˈkɑːtʃiˌoʊ, -tʃoʊ, bə-/; Italian: [dʒoˈvanni bokˈkattʃo]; 1313 – 21 December 1375) was an Italian author, poet, correspondent of Petrarch, and important Renaissance humanist. Boccaccio wrote a number of notable works, including the Decameron and On Famous Women. As a poet who wrote in the Italian vernacular, Boccaccio is particularly noted for his realistic dialogue, which differed from that of his contemporaries, medieval writers who usually followed formulaic models for character and plot.The details of Boccaccio's birth are uncertain. He was born in Florence or in a village near Certaldo where his family was from. He was the son of a Florentine merchant, Boccaccino di Chellino, and an unknown woman; he was likely born out of wedlock. Boccaccio's stepmother was called Margherita de' Mardoli.
