Cantos xxi. and xxii. are also noteworthy as bringing into prominence the agency of devils, and showing them actually at work. Ten are introduced and named; and some indication is given of their organisation. Dante’s skill is perhaps nowhere more apparent than in the way in which he has surmounted the difficulty of depicting beings in whom there is no touch of any good quality. They are plausible; and their leader, Malacoda, appears at first sight almost friendly. It is not until later that his apparent friendliness turns out to be a deliberate attempt to mislead. At the opening of Canto xxiii. we find the poets exactly half-way through Malebolge, on the rocky table-land, so to call it, which separates the fifth and sixth pits. They are quite solitary, for the first time in the course of their journey out of sight and hearing of any other beings; but still in fear of pursuit from the fiends whom they have just left. These do not, however, come up until just as the poets have begun the descent into the sixth pit, and here their power is at an end. In this pit are punished the hypocrites, who go in slow procession clad in cowls of gilded lead. Contrary to the usual practice the poets have in this case to descend to the bottom of the pit, the bridges being all broken away. Malacoda, the leader of the fiends in the last _bolgia_, had mentioned one, but (falsely) assured them that they would find a sound one further on. He also informed them that the destruction of the bridges had taken place 1266 years ago on the previous day, but five hours later than the time of speaking. This gives an important “time-reference.” There can be no doubt that the allusion is to the rending of the rocks at the moment of Our Lord’s death (_cf._ xii. 31-45), which took place at 3 P.M., so that we have 10 A.M. on Easter Eve fixed as the hour at which the poets meet with the devils of the fifth pit. Among the hypocrites Dante talks with two men who had jointly held the office of _Podestà_, or chief magistrate, at Florence in the year after his birth.[30] They belonged to opposite parties, and the double appointment had been one of the many expedients devised to restore peace; but it had not answered, and the two were suspected of having sunk their own differences of opinion, not to conciliate the factions, but to enrich themselves at the expense of the State. While talking to them Dante sees a figure fastened to the ground with three stakes, as though crucified. This, it is explained, is Caiaphas; Annas being similarly placed at another point of the circle. Dante and Virgil have to leave this pit as they entered it, by climbing over the rocks (Canto xxiv.); and from the minuteness with which this process is described (even to so characteristic a touch as “I talked as I went, to show that my wind was good,”) it has been thought that Dante was not without experience in mountain-craft.
