Now if we turn to Aristotle, we shall find that he understood the word [Greek: ei(lo/menon] or [Greek: i)llo/menon], and the proposition of Plato, exactly in this sense. Here I am compelled to depart from Buttmann, who affirms (p. 152), with an expression of astonishment, that Aristotle misunderstood the proposition of Plato, and interpreted [Greek: ei(lo/menon] or [Greek: i)llo/menon] as if it meant directly as well as incontestably, _rotating_ or _revolving_. Proklus, in his Commentary on the Timæus, had before raised the same controversy with Aristotle--[Greek: i)llome/nên de\, tê\n sphiggome/nên dêloi= kai\ sunechome/nên ou) ga\r ô(s A)ristote/lês oi)/etai, tê\n kinoume/nên] (Procl. p. 681). Let us, therefore, examine the passages of Aristotle out of which this difficulty arises. The passages are two, both of them in the second book De Coelo; one in cap. 13, the other in cap. 14 (p. 293 b. 30, 296 a. 25). 1. The first stands--[Greek: e)/nioi de\ kai\ keime/nên (tê\n gê=n) e)pi\ tou= ke/ntrou phasi\n au)tê\n i)/llesthai peri\ to\n dia\ panto\s tetame/non po/lon, ô(/sper e)n tô=| Timai/ô|** ge/graptai.** Such is the reading of Bekker in the Berlin edition: but he gives various readings of two different MSS.--the one having [Greek: i)/llesthai kai\ kinei=sthai]--the other ei(lei=sthai** kai\ kinei=sthai]. 2. The second stands, beginning chap. 14--[Greek: ê(mei=s de\ le/gômen prô=ton po/teron] (the earth) [Greek: e)/chei ki/nêsin ê)\ me/nei; katha/per ga\r ei)/pomen, oi( me\n au)tê\n e(\n tô=n a)/strôn poiou=sin, oi( d' e)pi\** tou= me/sou the/ntes i)/llesthai kai\ kinei=shai/ phasi peri\ to\n po/lon me/son.]
