Note 639 — CANTO XXIV.
James Romanes Sibbald translation
Front the bridge’s head: Further on they climb up again (Inf. xxvi. 13) by the projecting stones which now supply them with the means of descent. It is a disputed point how far they do descend. Clearly it is further than merely from the bridge to the lower level of the wall dividing the Seventh from the Eighth Bolgia; but not so far as to the ground of the moat. Most likely the stones jut forth at the angle formed by the junction of the bridge and the rocky wall. On one of the lowest of these they find a standing-place whence they can see clearly what is in the Bolgia.
