Ancient Greek
p. 6701 ⟨Ἀετίου⟩ · 11
Χρύσιππος ἀστραπὴν ἔξαψιν νεφῶν ἐκτριβομένων ἢ ῥηγνυμένων ὑπὸ πνεύματος, βροντὴν δ᾽ εἶναι τὸν τούτων ψόφον· ἅμα δὲ γίνεσθαι ἐν τῷ ἀέρι βροντήν τε καὶ ἀστραπήν, πρότερον δὲ τῆς ἀστραπῆς ἀντιλαμβάνεσθαι ἡμᾶς διὰ τὸ τῆς ἀκοῆς ὀξυτέραν εἶναι τὴν ὅρασιν·
1 ⟨Ἀετίου⟩ · 12
ὅταν δ᾽ ἡ τοῦ πνεύματος φορὰ σφοδροτέρα γένηται καὶ πυρώδης, κεραυνὸν ἀποτελεῖσθαι, ὅταν δὲ ἄθρουν ἐκπέσῃ τὸ πνεῦμα καὶ ἧττον πεπυρωμένον, πρηστῆρα γίγνεσθαι, ὅταν δ᾽ ἔτι ἧττον ᾖ πεπυρωμένον τὸ πνεῦμα, τυφῶνα.

Ἀριστοτέλης ἐξ ἀναθυμιάσεως καὶ τὰ τοιαῦτα γίνεσθαι τῆς ξηρᾶς. Ὅταν οὖν ἐντύχῃ μὲν τῇ ὑγρᾷ, παραβιάζηται δὲ τὴν ἔξοδον, τῇ μὲν παρατρίψει καὶ τῇ ῥήξει τὸν ψόφον, τῇ δ᾽ ἐξάψει τῆς ξηρότητος τὴν ἀστραπὴν παρίστησι.
Stobaeus, Volume I: Book I Chapter 29
p. 6711 ⟨Aëtius⟩: Chrysippus on sight and sound
Chrysippus held that lightning is the ignition of clouds rubbed against one another or torn apart by wind, and that thunder is the resulting noise. Thunder and lightning occur simultaneously in the air, but we perceive the lightning first because sight is quicker than hearing.866
1 ⟨Aëtius⟩: Chrysippus on degrees of heat
When the movement of the wind becomes more violent and fiery, a thunderbolt is produced. When the wind bursts out in a compact mass and is less intensely ignited, a fiery whirlwind occurs; when the wind is still less intensely ignited, a whirlwind.
1 ⟨Aëtius⟩: Aristotle
Aristotle held that these phenomena too arise from the dry exhalation. When it encounters the moist exhalation and forces its way out, the friction and rupture produce the noise, while the ignition of the dry matter produces lightning.
