Italian thumb|upright=0.9|The first five sonnets of Petrarch's Il Canzoniere Guittone d'Arezzo rediscovered the sonnet form and brought it to Tuscany, where he adapted it to Tuscan dialect when he founded the Siculo-Tuscan, or Guittonian school of poetry (1235–1294). He wrote almost 250 sonnets. Among the host of other Italian poets that followed, the sonnets of Dante Alighieri and Guido Cavalcanti stand out, but later the most famous and widely influential was Petrarch.
