The medieval Roman dialect belonged to the southern family of Italian dialects, and was thus much closer to the Neapolitan language than to the Florentine. A typical example of Romanesco of that period is "Vita di Cola di Rienzo" ("Life of Cola di Rienzo"), written by an anonymous Roman during the 14th century. Starting with the 16th century, the Roman dialect underwent a stronger and stronger influence from the Tuscan dialect (from which modern Italian derives) starting with the reigns of the two Medici popes (Leo X and Clement VII) and with the Sack of Rome in 1527, two events which provoked a large immigration from Tuscany. Therefore, current Romanesco has grammar and roots that are rather different from other dialects in Central Italy.
