A Franciscan, Nicolaus was the author of a complementary work (finished in 1444) to the Pisanella, the successful confessional that Bartholomeus de Chaimis had composed almost a century earlier. Nicolaus updated it according to the more recent canonical legislation, also including regular references to the Summa confessorum of Johannes Friburgensis. His enlarged version almost completely superseded the original Pisanella. There was furthermore a collection of penitential canons circulating under his name. However, as Nicolaus admitted in a prologue, he had simply copied it from the Summa of Astesanus (V. 32).
