Plutarchus de facie lunae cp. 5 p. 922d. (Lucius Pharnaci Stoico dicit, de aëre locutus) πρὸς πᾶσαν μὲν γάρ ἐστι ποιότητα καὶ δύναμιν εὐκέραστος ὑπὸ μανότητος, μάλιστα δὲ φωτὸς ἂν ἐπιψαύσῃ μόνον, ὥς φατε, καὶ θίγῃ, δι’ ὅλου τρεπόμενος ἐκφωτίζεται. Aëtius Plac. I 12, 4. Οἱ Στωϊκοὶ δύο μὲν ἐκ τῶν τεσσάρων στοιχείων κοῦφα, πῦρ καὶ ἀέρα· δύο δὲ βαρέα, ὕδωρ καὶ γῆν. κοῦφον γὰρ ὑπάρχει φύσει ὃ νεύει ἀπὸ τοῦ ἰδίου μέσου, βαρὺ δὲ τὸ εἰς μέσον. καὶ τὸ μὲν περίγειον φῶς κατ’ εὐθεῖαν, τὸ δ’ αἰθέριον περιφερῶς κινεῖται.
