Stefaneschi received his early education at Rome, and was sent to the University of Paris to pursue higher studies. After three years he received the degree of Master of Arts, and intended to devote himself to the study of philosophy and Holy Scripture, having already begun to teach at the university, when his parents recalled him to Italy in order that he should study canon and civil law.

Stefaneschi is best known as the author of , the earliest biography of Celestine V. The work is arranged in three parts, composed in dactylic hexameter, and based on Celestine's brief autobiography. The first part, written before Stefaneschi became a cardinal, is a three-volume account of Celestine's election, reign, and abdication. The second part, written five years later, gives an account of the election and coronation of Boniface VIII The final, three-volume part describes Celestine's life after his abdication, his canonization, and various miracles. In 1319, Stefaneschi united the three parts and sent them, along with a dedicatory epistle, to the prior and the monks of San Spirito at Sulmona, the mother-house of the Celestines. It was published along with a prose introduction giving details on Stefaneschi's life, and first edited by Papebroch, Acta Sanctorum, IV, May, 436-483.
