Praeparatio Evangelica (The Preparation of the Gospel)

'ALL the others say that the Earth is at rest.

'But Philolaus the Pythagorean says that it revolves round the fire in an oblique circle, in like manner as the Sun and Moon.

'Heracleides of Pontus, and Ecphantus the Pythagorean make the Earth move, not however by change of place, but by rotation, turning like a wheel on an axle, from west to east, about its own centre.

'Democritus: at first the Earth used to change its place, owing to its smallness and lightness; but as in the course of time it grew dense and heavy, it became stationary.'

After the utterance of these different opinions by the noble philosophers concerning the Earth, hear now what they say of the Sea.
