see a wonder, this mountain which God has set as a great boundary." King Alexander the son of Philip said, "How far is the extent of this mountain?" The old men say, "Beyond India it extends in its appearance." The king said, "How far does this side come?" The old men say, "Unto all the end of the earth." And wonder seized the great king at the council of the old men ... And he had it in his mind to make there a great gate. His mind was full of spiritual thoughts, while taking advice from the old men, the dwellers in the land. He looked at the mountain which encircled the whole world ... The king said, "Where have the hosts [of Gog and Magog] come forth to plunder the land and all the world from of old?" They show him a place in the middle of the mountains, a narrow pass which had been constructed by God ... 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. Prophecy about the Sabir Huns invasion (514 CE) The first ex-eventu prophecy about Gog and Magog in the Syriac Christian Legend relates to the invasion of the Sabir Huns in 514-15 CE (immediately before the second ex-eventu prophecy about the Khazars discussed below). In a paper supporting van Bladel's thesis on the direct dependency of the Dhu'l Qarnayn story on the Syriac Legend, Tommaso Tesei nevertheless highlights Károly Czeglédy's identification that this first prophecy already had a 6th-century CE existence as an apocalytic revelation involving the arrival of the Huns in a passage of the Lives of the Eastern Saints by John of Ephesus
