"When therefore thou beholdest not a small pebble, but the whole earth borne upon the waters, and not submerged, admire the power of Him who wrought these marvellous things in a supernatural manner! And whence does this appear, that the earth is borne upon the waters? The prophet declares this when he says, "He hath founded it upon the seas, and prepared it upon the floods."1416 And again: "To him who hath founded the earth upon the waters."1417 What sayest thou? The water is not able to support a small pebble on its surface, and yet bears up the earth, great as it is; and mountains, and hills, and cities, and plants, and men, and brutes; and it is not submerged!"

When Aquinas wrote his Summa, at the very beginning (Summa Theologica Ia, q. 1, a. 1; see also Summa Theologica IIa Iae, q. 54, a. 2), the idea of a round Earth was the example used when he wanted to show that fields of science are distinguished by their methods rather than their subject matter... "Sciences are distinguished by the different methods they use. For the astronomer and the physicist both may prove the same conclusion - that the earth, for instance, is round: the astronomer proves it by means of mathematics, but the physicist proves it by the nature of matter.History of Science: Shape of the Earth: Middle Ages: AquinasArchived 2006年9月3日, at the Wayback Machine."
