This paper explores the medieval debates concerning problems with the Aristotelian theory of the production and transmission of solar heat as presented in De Caelo II, 7 and Meteorologica I, 3. In these passages, Aristotle states that celestial heat is generated by the friction set up in the air by the motion of celestial bodies. This statement is difficult to reconcile with Aristotle’s cosmology, which presupposes that the heavenly bodies are not surrounded by air, but by aether, and that the celestial spheres are perfectly smooth, and therefore cannot cause any friction. In their commentaries on De Caelo and on Meteorologica, the Latin commentators elaborated a model that solves these difficulties. In this attempt, they invoke a non-mechanical principle, namely celestial influence.

天体区域的空气和摩擦:中世纪解决亚里斯多德论有关天体热量产生理论的难题的一些解决方案

本文探讨了中世纪关于辩论的争论,这些辩论涉及亚里士多德关于太阳热的产生和传输的理论的问题,如德卡洛二世7和气象学一3所述。在这些文章中,亚里斯多德说天体热是由摩擦建立而产生的。通过天体的运动在空中飞行。这种说法很难与亚里士多德的宇宙学调和,亚里士多德的宇宙学假定天体不是被空气包围,而是被以太包围,并且天球是完全光滑的,因此不会引起任何摩擦。在他们对De CaeloMeteorologica的评论中,拉丁评论员阐述了解决这些困难的模型。在这种尝试中,他们引用了非机械原理,即天体影响力。
