First and only incunabular edition. Ubertinus de Casali (1259-c. 1329) was one of the leaders of the Spirituali Franciscans in Italy. This work, composed around 1305, champions the rule of St Francis in its strictest sense and the poverty of Christ, both of which were not encouraged by various popes, and Ubertinus was exiled and later excommunicated as a result. His afterlife in literature encompassed Dante and Umberto Eco.

A similar fly stamp was used by the binder Jan Ryckaert, active in Ghent c. 1511-1546.
