Note 75 — Chapter III
Reading edition
The statement occurs in the commentary of Simplicius upon Aristotle's "De Caelo," and the Greek text reads 31,000; cf. ed. Heiberg, p. 506. But in a Latin translation by Moerbeka the figure is given as 1903, and this probably represents the original reading; cf. Lehmann-Haupt, "Zwei Hauptprobleme," pp. 109 f., 210, and Meyer, op. cit., p. 131.
