[622]. Arist. de Caelo, Γ, 2. 300 b 29 (R. P. 173 a). Cf. de Gen. An. Α, 17. 722 b 17, where fr. 57 is introduced by the words καθάπερ Ἐμπεδοκλῆς γεννᾷ ἐπὶ τῆς Φιλότητος. Simplicius, de Caelo, p. 587, 18, expresses the same thing by saying μουνομελῆ ἔτι τὰ γυῖα ἀπὸ τῆς τοῦ Νείκους διακρίσεως ὄντα ἐπλανᾶτο.

[624]. This is well put by Simplicius, de Caelo, p. 587, 20.

In Phys. p. 371, 33, he says the oxen with human heads were κατὰ τῆν τῆς Φιλίας ἀρχήν.
