[Footnote 59: Lit., “from the separation of the finest atoms of the air and from their movement when crowded together.”] [Footnote 60: So Roeper. Cruice agrees.] [Footnote 61: A. W. Benn, _op. cit._, p. 51, gives a readable account of Anaximander’s speculations in physics. Diels, _op. cit._, pp. 132, 133 shows in an excellently clear conspectus of parallel passages the different authors from whom Hippolytus took the statements in our text regarding the Ionians. The majority are to be found in Simplicius’ commentaries on Aristotle, Simplicius’ source being, according to Diels, the fragments of Theophrastus’ book on physics. Next in order come Plutarch’s _Stromata_ and Aetius’ _De Placitis Philosophorum_, many passages being common to both.] [Footnote 62: ὁμαλώτατος, _aequabilis_, Cr., “homogeneous.”] [Footnote 63: Lit., “whatever changes.”] [Footnote 64: Planets. See n. on p. 36 _supra_.] [Footnote 65: διὰ πλάτος. Cruice translates _ob latitudinem_, Macmahon “through expanse of space.”] [Footnote 66: μετεωριζόμενου. See n. on p. 42 _supra_.] [Footnote 67: So Diog. Laert., II, _vit. Anaxim._, c. 1. This is the feature of Anaximenes’ teaching which seems to have most impressed the Greeks.] [Footnote 68: παχυθέντα.] [Footnote 69: Diog. Laert., _ubi cit._, puts Anaximander in the 58th Olympiad (548 B.C.) and Anaximenes in the 63rd. This is more probable than the dates in our text. For Anaximenes’ sources, mostly Aetius and Theophrastus, see Diels’ conspectus mentioned in n. on p. 43 _supra_.] [Footnote 70: τὴν δὲ ὕλην γινομένην, _fieri materiam_, Cr.] [Footnote 71: τῆς ἐγκυκλίου κινήσεως. Macmahon says “orbicular,” but it means if anything centripetal and centrifugal, as appears in next sentence.] [Footnote 72: ὑποστῆναι. Hippolytus seems most frequently to use the word in this sense.] [Footnote 73: μετέωρον. See n. on p. 42 _supra_.] [Footnote 74: τά τε ἐν αὐτῇ ὕδατα ἐξατμισθέντα ... ὑποστάντα οὕτως γεγονέναι. I propose to fill the lacuna with καὶ πυκνωθέντα ἐν κοίλῳ. For a description of this cavity see the _Phædo_ of Plato, c. 138. I do not understand Roeper’s suggested emendation as given by Cruice.] [Footnote 75: There must be some mistake here. He has just said that the sun and moon are below the stars.] [Footnote 76: φωτισμοί, _illuminationes_, Cr. So Macmahon. It clearly means here “shinings forth again,” or “lightings up.”] [Footnote 77: Diog. Laert. quotes from Apollodorus’ _Chronica_ that Anaxagoras died in the 1st year of the 78th Olympiad, or ten years before Plato’s birth. For Hippolytus’ sources for his teaching, mainly Diog. Laert., Aetius and Theophrastus, see Diels, _ubi cit._] [Footnote 78: μῖγμα, not μῖξις. But of what could the creative mind be compounded before anything else had come into being?] [Footnote 79: ἐκ τῆς πυρῶσεως. Does he mean the heated air, and why should the earth form no part of the universe? Something is probably omitted here.]
