After this the Eagle proceeds to indicate whose are the spirits which compose its eye. These with one exception are all great sovereigns of ancient and recent times. The exception is remarkable. In Hell we found several cases in which mythological or fictitious personages were treated on a footing of absolute equality with those who had a perfect historical claim to the distinction; but the appearance in the Christian Heaven of a man whose very name is preserved merely in a single line of the _Æneid_ strikes us with astonishment. For being recorded by Virgil as the most righteous man among the Trojans, Rhipeus takes his place beside David, Hezekiah, Constantine, and the “good king” William II. of Sicily. When the time comes for the ascent to be resumed, Dante notices that Beatrice smiles no longer. On the threshold, as she explains, of the seventh heaven, the lustre of her smile would be more than his eyes could endure. Here, in Saturn, a ladder is seen, reaching to the next sphere. We learn that this is identical with the ladder seen by Jacob in his vision; and down it are descending the spirits of such as in this world had lived the contemplative life in full perfection. The chanting which has been audible in the other spheres is here silent--no doubt in order to symbolise the insensibility to outward impressions of the soul rapt in contemplation. The speakers in this group are St. Peter Damian and St. Benedict; both of whom have severe words to say as to the corruption of the monastic orders. The company of saints reascend (Canto xxii.): and Dante and Beatrice follow them, mounting by the ladder, but, as it would appear, with no perceptible lapse of time. The eighth heaven, that of the Fixed Stars, is reached in the sign of the Twins; under which Dante himself had been born. At this point Beatrice directs him, before entering on the final blessedness of heaven, and doubtless with the ulterior view of leading him to a just sense of the insignificance of earthly things, to look back over the course which he has traversed. A very distinct stage of the journey is here reached, and, as has been already noticed, we are entering that one of the celestial spheres in which Dante makes the longest stay.
