The plot represents the Indian hermit Kalanus as believing devoutly that he has discovered in Alexander, who has just reached India on his triumphal progress through Asia, a revelation of Brahma's eternal light. He approaches the king in humble adoration, follows him at a respectful distance in his march through the desert as far as Pasargada, where he has the good fortune to be led once more into the presence of the mighty ruler, and falling upon his bended knee, he addresses him with the titles, "God, Ruler, Prince of Wisdom, King of Power." Alexander, recognizing the rare worth of the man, with kindly purpose attaches him to his person, and permits him to participate in a festival he holds that same evening. At this celebration, which the poet has portrayed with marked success, there are present some beautiful Greek courtesans, who sing the praises of Alexander, and amid loud rejoicing ransack his jewel-casket. To his profound astonishment and infinite horror, Kalanus now discovers that the great potentate, in whom he had seen the incarnate god, is neither inclined to shun the intoxication slumbering in the dregs of the flowing goblet, nor is master of the demon that lies concealed behind the mask of female beauty. In the first moment of consternation he plunges, knife in hand, at one of the courtesans, but is soon disarmed. Like one paralyzed he stands rooted to the spot when the banquet is over, not only bitterly disabused in his faith, but crushed with contrition to think that he should have confounded Brahma with a weak and mortal man like himself. Through self-annihilation alone can he hope to atone for his sin, and return to the god. He resolves, after Indian fashion, to immolate himself on the flaming pyre.
