Plato's Doctrine Respecting the Rotation of the Earth and Aristotle's Comment Upon That Doctrine

The dissertation examines whether Plato’s Timæus affirms or implies the earth’s rotation, in what sense, and what cosmical role the earth performs. It analyses the disputed Greek passage and traces ancient and later readings — including Aristotle’s refutation of a rotating earth, defenders who read rotation into Plato, and commentators such as Alexander of Aphrodisias, Proclus, Simplicius, Cicero, and Plutarch — then surveys modern philological debate, notably Gruppe and Boeckh. The author rejects the claim that Plato endorses terrestrial rotation or heliocentrism, proposes an alternative interpretation of the passage, and shows how the controversy illuminates classical approaches to cosmology and scientific explanation.
