 Guido Guinizelli is considered the founder of the "Dolce Stil Novo", a school that added a philosophical dimension to traditional love poetry.This new understanding of love, expressed in a smooth, pure style, influenced Guido Cavalcanti and the Florentine poet Dante Alighieri, who established the basis of the modern Italian language; his greatest work, the "Divine Comedy", is considered among the foremost literary statements produced in Europe during the Middle Ages; furthermore, the poet invented the difficult "terza rima".The two great writers of the 14th century, Petrarch and Giovanni Boccaccio, sought out and imitated the works of antiquity and cultivated their own artistic personalities.
