Abstrakt EN: Aristotle reported that among the ancients, Anaximander of Miletus had said that the earth stays motionless in place because of symmetry uniformity. Aristotle argued that what is situated in the middle and is equally distance from everything has no inclination to move up but rather than down or sideways. This argument was often believed to be one of the first instances of an argument based on the principle of sufficient reason. Hippolytus adds that, according Anaximander, the earth is suspended, supported by nothing, because its equal distance from everything. But the same argument is disputably ascribed also to Democritus. Moreover, Anaximander´s successor Anaximenes already explained the position of the earth because it rests on the air like lid. Furthermore, Simplicius said that Anaximander explained the stability of the earth both by its symmetrical position and by the support of the air. Can we pose the question if Aristotle made a mistake in his report? From doxography we know that Anaximander´s conception of cosmology supposed a flat earth at the centre of the concentric wheels of the celestial bodies, the sun, moon and stars. In my talk, I will speak on the explanation of the immobility of the earth which can be firstly based on the very conception of cosmogony and the assumption of the role of the air, mist. Further, I will mainly focus on the argument which is valid only in the plan view (horizontal cross?section) of the universe. In this connection, I will discuss the question of the stability of the earth as it is related to the existence of the map of the universe.
