The initial boost given by the Sicilian poets from the Svevs' court, the first to use a standardised vernacular to make art poetry will be passed on to many others: and all of them, not just the pedantic imitators of the Siculo-Tuscan school (such as Bonagiunta Orbicciani) but also Guinizzelli, the poets of Dolce Stil Novo and more widely all writers of verse, will have to deal, though by different degrees, with the Sicilian models, so that some peculiarities will be assimilated into standard usage of Italian poetry."
