Giovanni Boccaccio was an Italian writer, poet, correspondent of Petrarch, and an important Renaissance humanist. Boccaccio wrote a number of notable works, including "The Decameron" and "On Famous Women". He wrote his imaginative literature mostly in Tuscan vernacular, as well as other works in Latin, and 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.
