[65] Franke and Hentze reject this and the following line, on the ground that the difficulty lies not in the descent, but in the ascent on the opposite side. But for a chariot the descent of a “κρημνὸς ἐπηρεφής” is as serious a matter as the ascent. The idea seems to be, ‘we cannot even get into the trench with horses, nor, even if we get across, can we fight on the other side; for the space between the wall and the trench is a “στεῖνος”, too small for chariots.’
