He is best known for recording one of the earliest Petrarchist poems in Croatian, written using Glagolitic script.
He was a priest, but has been also mentioned (1456) as a notary for the city and the county of Zadar.
The only preserved - though in a bit damaged state - Vidulić's poem in Croatian, Ako mi ne daš lik, composed in six dodecasyllabic quatrains, is the proof of the existence of troubadour-Petrarchan school of poetry in the middle of 15th century in Zadar, beside the city of Dubrovnik.
The poem was found written on one official document and, of course, it is not certain whether Vidulić was the author or just a scribe.
Vidulić was also an educated humanist, used Glagolitic script, and was in a certain way a predecessor of Petar Zoranić.
