While papal declarations made the Porziuncola Indulgence indisputable from the juridico-canonistic standpoint, its historical authenticity (i.e. origin from St Francis) remains in question. None of the old legends of St Francis mentions the Indulgence, nor does any contemporary document mention it. The oldest document mentioning the Indulgence is a notary's deed of 31 October 1277, in which Blessed Benedict of Arezzo (whom St Francis himself received into the order) testifies that he had been informed by Brother Masseo (a companion of St Francis) that Pope Honorius III granted the indulgence at Perugia. Later testimonies include those of Jacob Cappoli concerning Brother Leo, of Oddo of Acquasparta, Peter Zalfani, Peter John Olivi (who wrote a scholastic tract defending this indulgence about 1279), John of Laverna, Ubertino da Casale, and Francis of Fabriano (whose testimony goes back to the year 1268).
