Note 589 — CANTO XXI.
James Romanes Sibbald translation
The next rib: Malacoda informs them that the arch of rock across the Sixth Bolgia in continuation of that by which they have crossed the Fifth is in ruins, but that they will find a whole bridge if they keep to the left hand along the rocky bank on the inner edge of the pitch-filled moat. But, as appears further on, he is misleading them. It will be remembered that from the precipice enclosing the Malebolge there run more than one series of bridges or ribs into the central well of Inferno.
