  2. Celestial spheres - Wikipedia

    en.wikipedia.org/wiki/Celestial_spheres

    In his Metaphysics, Aristotle developed a physical cosmology of spheres, based on the mathematical models of Eudoxus. In Aristotle's fully developed celestial model, the spherical Earth is at the centre of the universe and the planets are moved by either 47 or 55 interconnected spheres that form a unified planetary system, [19] whereas in the ...

    Sometimes Aristotle seems to regard them as living beings with a rational soul as their form [2] (see also Metaphysics, bk. XII). Aristotle proposed a geocentric model of the universe in De Caelo. The Earth is the center of motion of the universe, with circular motion being perfect because Earth was at the center of it.

    en.wikipedia.org/wiki/Aristotelian_physics

    Aristotelian physics is the form of natural philosophy described in the works of the Greek philosopher Aristotle (384–322 BC). In his work Physics, Aristotle intended to establish general principles of change that govern all natural bodies, both living and inanimate, celestial and terrestrial – including all motion (change with respect to place), quantitative change (change with respect to ...

  5. Concentric spheres - Wikipedia

    en.wikipedia.org/wiki/Concentric_spheres

    The cosmological model of concentric (or homocentric) spheres, developed by Eudoxus, Callippus, and Aristotle, employed celestial spheres all centered on the Earth. [1] [2] In this respect, it differed from the epicyclic and eccentric models with multiple centers, which were used by Ptolemy and other mathematical astronomers until the time of Copernicus.

    This understanding was accompanied by models of the Universe that depicted the Sun, Moon, stars, and naked eye planets circling the spherical Earth, including the noteworthy models of Aristotle (see Aristotelian physics) and Ptolemy. [8] This geocentric model was the dominant model from the 4th century BC until the 17th century AD.

    Aristotle also tried to determine whether the Earth moves and concluded that all the celestial bodies fall towards Earth by natural tendency and since Earth is the centre of that tendency, it is stationary. [26] Plato seems to have obscurely argued that the universe did have a beginning, but Aristotle and others interpreted his words ...

    Aristotle, drawing on the mathematical model of Eudoxus, proposed that the universe was made of a complex system of concentric spheres, whose circular motions combined to carry the planets around the Earth. [36] This basic cosmological model prevailed, in various forms, until the 16th century.
