Note 28 — BOOK I [METEORS, HALO, RAINBOW, MOCK SUN, Etc.]

The reading of the MSS. is admittedly corrupt. I have followed Ruhkopf’s conjecture, though without conviction. The argument seems to require dissimilis = unlike, or non similis (cf. c. v. 13), instead of similis = like (“resemble” in the text): in that case the meaning would be: how an image unlike the original ought to be reflected from the cloud as from a mirror. Cf. § 13 below.
