Praeparatio Evangelica (The Preparation of the Gospel)

'ANAXIMANDER: the Sun itself is equal to the Earth, but the orbit from which it breathes out its fire, and by which it is carried round, is twenty-seven times as large as the Earth.

'Anaxagoras: many times as large as Peloponnesus.

'Heracleitus: the breadth of a man's foot.

'Epicurus again says that the aforesaid descriptions are all possible: or else that it is of the same size as it appears, or a little greater or less.'
