Note 37 — Chapter VI · THE STUDY OF NATURE. FUNDAMENTAL POSITIONS.
Oswald J. (Oswald Joseph) Reichel translation
Stob. i. 356; Plut. Plac. ii. 2, 1; i. 6, 3; Diog. 140; Cleomed. Met. pp. 39 and 46; Heraclit. Alleg. Hom. c. 46. Ibid. on the perfection of this form and its adaptation for motion. Comparing Achil. Tat. Isag. 130, C, Plut. Plac. ii. 2, 1 (Galen. Hist. Phil. c. 11), with the passages on p. 201, note 4, it appears probable that Cleanthes believed in a spherical form of the earth. According to Ach. Tat. Isag. 152, A, who probably has the Stoics in view, the axis of the world consists of a current of air passing through the centre. On the division of the heaven into five parallel circles, and that of the earth into five zones, conf. Diog. 155; Strabo, ii. 2, 3, p. 95. ↑
