The Four Books of Sentences
This book is in Latin.
The standard textbook of medieval theology, on which every master from Alexander of Hales to Bonaventure and Aquinas lectured: the Trinity, creation and sin, the Incarnation, virtues and commandments, the sacraments and the last things, in 182 distinctions. The Latin is the Migne text (Patrologia Latina 192, 1855), from a machine-corrected OCR, not the Quaracchi (1916) or Grottaferrata (1971-81) critical edition. Migne's closing list of the articles in which the Master is not followed is included. No English translation in the public domain exists.
