The poet, seeming to realize that the most difficult part of his tale is now to tell, again invokes the native Muse, and relates how the lovers, couched on the wings of the raven steeds, enter on their flight a zone of mists enfolding the couch of Sleep, who has been drawn from his cave by the rumour of the coming nuptials of a goddess with a mortal. The narrative is here very obscure, but seems to run thus. Alike the magic steed and the lovers reclining on their wings yield to the influence of sleep, but still drift on their aerial course. As they drift, Endymion dreams that he has been admitted to Olympus. In his dream he drinks of Hebe's cup, tries the bow of Apollo and the shield of Pallas; blows a bugle which summons the Seasons and the Hours to a dance; asks whose bugle it is and learns that it is Diana's; the next moment she is there in presence; he springs to his now recognized goddess, and in the act he awakes, and it is a case of Adam's dream having come true; he is aware of Diana and the other celestials present bending over him. On the horse-plume couch beside him lies the Indian maiden: the conflict between his two loves is distractingly renewed within him, though some instinct again tells him that he is not really untrue to either. He embraces the Indian damsel as she sleeps; the goddess disappears; the damsel awakes; he pleads with her, says that his other love is free from all malice or revenge and that in his soul he feels true to both. What is this soul then? Whence Came it? It does not seem my own, and I Have no self-passion nor identity. This charge, be it noted, is one which Keats in his private thoughts was constantly apt to bring against himself. Foreseeing disaster and the danger of losing both his loves and being left solitary, Endymion nevertheless rouses the steeds to a renewed ascent. He and the damsel are borne towards the milky way, in a mystery of loving converse: the crescent moon appears from a cloud, facing them: Endymion turns to the damsel at his side and finds her gone gaunt and cold and ghostly: a moment more and she is not there at all but vanished: her horse parts company from his, towers, and falls to earth. He is left alone on his further ascent, abandoned for the moment by both the objects of his passion, the celestial and the human. His spirit enters into a region, or phase, of involved and brooding misery and thence into one of contented apathy: he is scarcely even startled, though his steed is, by a flight of celestial beings blowing trumpets and proclaiming a coming festival of Diana. In a choral song they invite the signs and constellations to the festival: (the picture of the Borghese Zodiac in Spence's _Polymetis_ has evidently given Keats his suggestion here). Then suddenly Endymion hears no more and is aware that his courser has in a moment swept him down to earth again.
