Praepositivus, Pietro an Italian theologian, who flourished near the opening of the 13th century, was a native of Cremona, taught theology in the schools of Paris, and was at the close of 1206 chancellor of the Church of Notre Dame. In 1209 we find Jean de Cantelis in his place. His chief work is a Summans Theoloix, of which two or three pages only were printed; they are in the Penitential of Theodore. There are numerous copies of it at Oxford and in the National Library at Paris. Praepositivus died at Paris in 1209 or 1217. See Tiraboschi, Storia de la Letter.
