[Footnote 54: So Diog. Laert., II, _vit. Anaximander_, c. 1, _verbatim_.]
[Footnote 55: κόσμοι. He therefore believed in a plurality of worlds.]
[Footnote 56: οὐσία. It may here mean essence or being. A good discussion of the changes in the meaning of the word and its successors, ὑπόστασις and πρόσωπον, is to be found in Hatch, _op. cit._, pp. 275-278.]
[Footnote 57: μετέωρον, a phenomenon in the heavens, but also something hung up or suspended.]
[Footnote 58: στρογγύλον, used by Theophrastus for logs of timber.]
[Footnote 59: Lit., “from the separation of the finest atoms of the air and from their movement when crowded together.”]
[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 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 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.]
