When this Gate has been passed through, a narrow chasm between the rocks has to be climbed, and the passage is so difficult that it is at least an hour before the poets emerge on the open space of the First Cornice. For the waning moon has already set, and as she has lost another half hour or so during the night, the time of her setting this morning was about 9 a.m. When Dante next notices the position of the sun, which he is too intent to do for some time, they have travelled some distance along the First Cornice, with its outer edge on their right, and the sixth handmaid is returning from the service of the day, that is, the sixth hour is ended: it is midday, and they have spent nearly three hours here, looking at the rock sculptures and conversing with the spirits. The ascent to the Second Cornice is made with marvellously little fatigue, as Virgil had promised. There they at first find no one to direct them, so Virgil looks at the sun, and turns westward towards it, taking it as their guide, and they walk for about a mile before encountering any spirits in this circle. The stairway to the next Cornice is reached at the time of vespers, that is, 3 p.m.; and Dante describes the position of the sun by saying that the portion of sky which it still had to traverse before evening was equal to the portion which is brought into view between the beginning of the day and the end of the third hour, that is, it was three hours before sunset; and he compares this ceaseless motion of the sky, which according to the Ptolemaic system caused the motion of the sun, to an ever-playing child. We need not particularly enquire whether he is thinking of the heaven of the sun, or the Primum Mobile: it may be either, but is most likely simply the diurnal movement in general, made strikingly evident by the sun. The sun’s rays now strike their faces, for they have so far circled the mountain that they are walking towards the west; “Vespero là”[472] means in Purgatory, and “qui”[473] is Italy, where it is midnight now. ------------------------------------------------------------------------ [472] “Vespers there.” [473] “Here.” ------------------------------------------------------------------------ The sun is low when they reach the third Cornice, and when they emerge from the dense cloudy fog which here envelopes the spirits, Dante gradually sees the ball of the sun as when mists clear away, and he sees that it is just about to set. In fact the low shores at the foot of the mountain are already in shadow. Virgil urges that they make the ascent to the next Circle before darkness comes, and, as each ascent is easier than the last, they are able just to reach the summit before the sun is quite gone. Here Dante sees the stars begin to appear, while he is wondering at the strange law which robs him of power to proceed (as Sordello had warned them) after the sun has set.
