Abstrakt EN: According to Aristotle, Anaximander of Miletus explained the immobile position of the Earth in the universe by uniformity. Simplicius, on the other hand, claims that the Earth was supported by air. Given the overall structure of Anaximander’s universe, where the circles of celestial bodies are located concentrically around a flat Earth, Aristotle’s argument about uniformity cannot be valid. The air mentioned by Simplicius, meanwhile, played a pivotal role in Anaximander’s cosmology because it participated in the creation of celestial bodies and at the same time filled the entire universe. One could thus assume that Anaximander indeed believed the Earth to be resting on air. Unlike other cosmological conceptions of the sixth century BC, however, Anaximander is said to have believed that celestial bodies during their motion pass also under the Earth. This could be linked not only to a description of their compact structure as circles but also their obliquity and description of their size and distance. One can thus assume that Aristotle’s argument is in fact based on an erroneous interpretation of Anaximander’s notion of a universe of concentric circles located around the Earth, with the circles passing even under it.
