Note 32 — Chapter VI · THE STUDY OF NATURE. FUNDAMENTAL POSITIONS.
Oswald J. (Oswald Joseph) Reichel translation
Stob. i. 346: τὸ μὲν περίγειον φῶς κατ’ εὐθεῖαν, τὸ δ’ αἰθέριον περιφερῶς κινεῖται. See p. 202, 3. It is only of terrestrial fire that Zeno can (Stob. Ecl. i. 356) say, it moves in a straight line. Cleanthes even attributed to the stars the spherical shape, which on the strength of this passage he attributes to it. See Plut. Plac. ii. 14, 2; Stob. i. 516; Ach. Tat. Isag. 133, B. ↑
