ANGELUS DE CLAVASIO (1411-1495). Summa angelica de casibus conscientiae. Chivasso: Jacobinus Suigus de Suico, 13 May 1486.

First edition of the only 15th-century book printed in Chivasso, in a contemporary binding with otherwise unrecorded quire of errata. The principal work of Angelo Carletti of Chivasso, a noted theologian of the Friars Minor, the Summa contains 659 articles in alphabetical order forming the equivalent of a dictionary of moral theology. It attracted a wide readership, going through 31 editions up to 1520—the year it was publicly burned by Martin Luther as a paragon of Catholic orthodoxy. This is the variant which reads “permutet.” This copy contains three leaves of what seems to be errata, unreported in bibliographies. Not in the Bavarian State Library. HC 5382; BMC VII 1111; GW 1923; Bod-inc A-285; IGI 559; Goff A-713; ISTC ia00713000.
