Hesburgh Libraries has recently acquired an interesting and extremely rare early modern work, Alessandro Ludovisi’s Catalogus Excommunicationum, quae extra Bullam Coenae Domini sunt reservarae Papae, vel Episcopo, vel Nemini, iussu illustrissimi… (Bononiae, 1613). Ludovisi (1554-1623), a native of Bologna who would later become Pope Gregory XV from 1621-1623, compiled what is essentially a handbook that details which types of persons—religious and secular—can be excommunicated, for what reasons, and who has the particular authority to do so.
For example, chapter one concerns the excommunication of prelates (cardinals, bishops, nuncios, etc.) by the Pope himself; chapter two covers lesser clerics, chapter four, nuns and chapter six, Inquisitors. Chapter seven deals with secular lords and nobility, while chapter eight discusses various professions, including magistrates, university rectors, governors, and scholars. Chapter ten concerns all those who can be excommunicated by a bishop alone.
In addition, manuscript annotations add interest to this particular copy, attesting perhaps to various canon law interpretations prevalent during this period.
We have found no other copies of this title held by other North American libraries.
