Note 141 — BOOK II. AN ACCOUNT OF THE WORLD AND THE ELEMENTS.

“nunc relicto mundi ipsius corpore, reliqua inter cœlum terrasque tractentur.” I have already had occasion to remark upon the various modes in which the author uses the word mundus; by cœlum, in this passage, he means the body or region beyond the planets, which is conceived to contain the fixed stars. Sphæra, in the preceding sentence, may be supposed to mean the celestial globe.
