Rambertino di Guido Buvalelli[1] (1170 or 1180 – September 1221), a Bolognese judge, statesman, diplomat, and poet, was the earliest of the podestà-troubadours of thirteenth-century Lombardy.
He is usually regarded as the first native Italian troubadour, though Cossezen and Peire de la Caravana may precede him.
Rambertino was a law student at the University of Bologna in his youth and became attached to the Este court not long after.
In 1212 he was serving as ambassador for Pope Innocent IV's cardinal-legate Gerardo da Sesso, soon to be Bishop of Vercelli, to Modena, but by May he had returned to Bologna.
Hoc de mense septembris obit dominus Lambertus Buvalelli potestas Verone.
He did have contact with other troubadours, notably Elias Cairel, whom at the end of Toz m'era de chantar gequiz he asks to bring the poem to Beatrice at the Este court.
