The questions on Aristotle´s De Caelo by Peter of Auvergne (d. 1304) contain a wealth of material for the study of the reception of De Caelo in the 13th century and Peter´s own views in cosmology and natural philosophy. The book contains a critical edition of these questions (part II) along with an extensive introduction to the text (part I). The first section of part I deals with Peter of Auvergne´s life and work, the reception of De Caelo in the 13th century, the different treatises on De Caelo that are attributed to Peter, and the composition and sources of Peter´s questions on De Caelo. The second section of the introduction contains an interpretative study of these questions. Here, the book discusses Peter´s division of the sciences, his cosmological theories concerning the universe, the heavens, the earth and the sublunary world, and some general topics in medieval natural philosophy. The third section of part I provides an introduction to the critical edition.
Part II contains the critical edition of two different sets of questions on De Caelo attributed to Peter of Auvergne. One set is preserved in the manuscripts Vienna, Dominikanerkonvent 150/120, fols. 47ra-68vb and Paris, Bibliothèque Mazarine 3493, fols. 95ra-136rb; the other set is preserved in the manuscripts Leipzig, Universitätsbibliothek 1386, fols. 91va-102vb and Prague, Knihovny Metropolitní 1320 (L.
