Note 1 — PREFATORY NOTE.
Reading edition
Most fruitful among these were those given by Plato in the Timæus. See, also, Grote on Plato's doctrine of the rotundity of the earth. Also Sir G. C. Lewis's Astronomy of the Ancients, London, 1862, chap. iii., sec. i. and note. Cicero's mention of the antipodes and reference to the passage in the Timæus are even more remarkable than the original, in that they much more clearly foreshadow the modern doctrine. See Academic Questions, ii., xxxix. Also, Tusc. Quest., i., xxviii., and v., xxiv.
