Vacuum
See main: Nature abhors a vacuum
In c.150AD, pseudo-Plutarch (Ѻ), in his The Opinions of the Philosophers, book 1, chapter 18 “Of a Vacuum”, stated the following: [1]

“All the natural philosophers form Thales to Plato rejected a vacuum. Empedocles says that there is nothing of a vacuity in nature, nor anything superabundant. Leucippus, Democritus, Demetrius, Metrodorus, and Epicurus as say that the atoms are in number infinite; and that a vacuum is infinite in magnitude. The stoics say that within the compass of the world there is no vacuum, but beyond it the vacuum is infinite. Aristotle says that the vacuum beyond the world is so great that the heaven has liberty to breath into it, for the heaven is fiery.”

In 1672, Otto Guericke, in his chapter on “Empty Space” cites some of this passage, e.g. mentioning Metrodorus. [2]
