      Venise B. Locatellus pour O. Scotus 1502 In-folio de 84 ff.; daim naturel, double encadrement de filets à froid sur les plats (reliure moderne, genre ancien). Adams G-1033 (sous Gratia Dei). Quatrième édition (l'originale publiée à Padoue en 1476). Gaetano da Thiene (1387-1465), de Vicence, fut élève de Paolo Nicoletti à Venise. Il fut l'un des principaux propagateurs de la doctrine d'Averroès en Italie et a abondament commenté les oeuvres scientifiques d'Aristote. "Books I and II of the De caelo treat of astronomical theories; III and IV, of the elements. Drawing upon theories advanced by his predecessors, Aristotle's theories in general may be summarized as representing the earth as fixed at the center of a spherical universe, with the spheres of the moon, Mercury, Venus, the sun, Mars, Jupiter, and Saturn in orbit around the earth, and beyond them the sphere of the fixed stars and the realm of the primum movens or force which, every twenty-four hours, caused the planetary spheres to complete their revolutions, while each planet with an individual motion moved at times slightly retrograde." (Stillwell, The Awakening Interest in Science during the First Century of Printing, pp. 11-12). En fin de volume se trouve le De materia coeli d'Egidio Colonna († 1316), connu aussi sous le nom de Giles de Rome, "especially noteworthy.[it] takes the position -against Aristotle, Thomas Aquinas, and the majority of contemporary scholars- that celestial matter is identical to that of the sublunary world." (D.S.B., V, p. 403). Quelques figures dans le texte et belles initiales à fond noir. Bon exemplaire.
