Flat Earth beliefs in the Early Christian Church varied and the Fathers of the Church shared different approaches. Those of them who were more close to Aristotle and Plato's visions, like Origen, shared peacefully the belief in a spherical Earth. A second tradition, including St Basil and St Augustine, accepted the idea of the round Earth and the radial gravity, but in a critical way. In particular they pointed out a number of doubts about the antipodes and the physical reasons of the radial gravity. However, a flat Earth approach was more or less shared by all the Fathers coming from the Syriac area, who were more inclined to follow the letter of the Old Testament. Diodore of Tarsus (?–390 AD), Cosmas Indicopleustes (6th century), and Chrysostom (347–407 AD) belonged to this flat Earth tradition.
