Even so, sometime around 1470 Pulci needed more money and went into the service of Roberto Sanseverino d'Aragona, a northern condottiere.
In 1478 (after the assassination of Lorenzo's brother Giuliano during the Pazzi Conspiracy), Pulci, riding on the coattails of the city's current anti-clericalism, wrote a poem dedicated to Lucrezia Tornabuoni that fulminated against Pope Sixtus IV's Rome.
His brother Luca's works, all in the Italian language, include Pistole, Driadeo d'amore, and Cyriffo Calvaneo.
The subject was loosely derived from the Carolingian epic tradition, but Pulci drew many characters and motives also from the popular poems usually sung by storytellers in Florence's piazzas and developed a rich series of comic and parodistic episodes.
This language is very far from the early Renaissance classicistic model, proposed by Poliziano in those same years in the Medicis' court.
