Hicetas Syracosius, ut ait Theophrastus [Frag. 240 FHS&G] caelum solem lunam stellas supera denique omnia stare censet, neque praeter terram rem ullam in mundo moveri: quae cum circum axem se summa celeritate convertat et torqueat, eadem effici omnia quasi stante terra caelum moveretur.Two Earths (D2)

HICETASD The Motion of Our Earth (D1)
D1 (50.1) Theophrastus in Cicero, Prior Academics
Hicetas of Syracuse, as Theophrastus says, thinks that the heavens, the sun, the moon, the stars, in short everything on high, is at rest and that nothing in the world moves except the earth: because this turns and rotates on its axis at an extremely high speed, exactly the same effect is produced as if the heavens were moving while the earth was at rest.Two Earths (D2)
D2 (50.2) Aëtius
[. . .] Hicetas the Pythagorean: [scil. that there are] two [scil. earths], this one and the counter-earth.
