[410] For δὲ κατ᾽ Aristarchos read “δ᾽ ἐξ”, and for “ἐς ἐπί”, on the ground that the prepositions “κατά” and “ἐς” are only appropriate when used of a journey from Olympos to the lower earth, not of a passage from one mountain-top to another, “ἀπ᾽ ἴσου ἐπ᾽ ἴσον”. But the whole line is interpolated here from 15.79, as is shown by the MSS. which omit it.
