[978]. From Diog., loc. cit. (supra, p. 391), it appears that he dealt with the question of the greater frequency of lunar as compared with solar eclipses. It seems to have been this which led him to make the circle of the moon smaller than that of the stars.
[979]. Diels pointed out that Leukippos’s explanation of thunder (πυρὸς ἐναποληφθέντος νέφεσι παχυτάτοις ἔκπτωσιν ἰσχυρὰν βροντὴν ἀποτελεῖν ἀποφαίνεται, Aet. iii. 3, 10) is quite different from that of Demokritos (Βροντὴν ... ἐκ συγκρίματος ἀνωμάλου τὸ περιειληφὸς αὐτὸ νέφος πρὸς τὴν κάτω φορὰν ἐκβιαζομένου, ib. 11). The explanation given by Leukippos is derived from that of Anaximander, while Demokritos is influenced by Anaxagoras. See Diels, 35 Philol.-Vers. 97, 7.
[980]. Aet. iv. 9, 8, οἱ μὲν ἄλλοι φύσει τὰ αἰσθητα[αἰσθητα], Λεύκιππος δὲ Δημόκριτος καὶ Ἀπολλώνιος νόμῳ. See Zeller, Arch. v. p. 444.
[981]. Chap. IV. p. 200, [n. 443]. The remarkable parallel quoted by Gomperz (p. 321) from Galilei, to the effect that tastes, smells, and colours non sieno altro che puri nomi should, therefore, have been cited to illustrate Parmenides rather than Demokritos.
[983]. For these see Sext. Math. vii. 135 (R. P. 204).
[984]. Sext. vii. 140, “ὄψις γὰρ ἀδήλων τὰ φαινόμενα,” ὥς φησιν Ἀναξαγόρας, ὃν ἐπὶ τούτῳ Δημόκριτος ἐπαινεῖ.
[985]. See Zeller, “Zu Leukippus” (Arch. xv. p. 138). The doctrine is attributed to him in Aet. iv. 13, 1 (Dox. p. 403); and Alexander, de Sensu, pp. 24, 14 and 56, 10, also mentions his name in connexion with it. This must come from Theophrastos.
