day, life, and memory contemned. In this dialogue lies the key to the philosophy which Wagner has proclaimed in the tragedy. In Wagner's exposition of the prelude we saw that he wishes us to observe "the one glimmering of the highest bliss of attainment" in the "surrender of being," the "final redemption into that wondrous realm from which we wander farthest when we try to take it by force." For this realm he chooses death and night as symbols, but what he means to imply is the nirvana of Buddhistic philosophy, the final deliverance of the soul from transmigration. Such love as that of Tristan and Isolde presented itself to Wagner as ceaseless struggle and endless contradiction, and for this problem nirvana alone offers a happy outcome; it means quietude and identity. In vain does Brangäne sing her song of warning from the tower; the lovers have been transported beyond all realization of their surroundings; they sing on, dream on in each other's arms, until at the moment of supremest ecstasy there comes a rude interruption. Kurwenal dashes in with a sword and a shout: "Save thyself, Tristan!" the king, Melot, and courtiers at his heels. Day, symbol of all that is fatal to their love, has dawned. Tristan is silent, though Marke bewails the treachery of his nephew and his friend. From the words of the heart-torn king we learn that he had been forced into the marriage with Isolde by the disturbed state of his kingdom, and had not consented to it until Tristan, whose purpose it was thus to quiet the jealous anger of the barons, had threatened to depart from Cornwall unless the king revoked his purpose to make him his successor, and took unto himself a wife. Tristan's answer to the sorrowful upbraidings of his royal uncle is to obtain a promise from Isolde to follow him into the "wondrous realm of night." Then, seeing that Marke does not wield the sword of retribution, he makes a feint of attacking Melot, but permits the treacherous knight to reach him with his sword. He falls wounded unto death. The last act has been reached. The dignified, reserved knight of the first act, the impassioned lover of the second, is now a dream-haunted, longing, despairing, dying man, lying under a lime tree in the yard of his ancestral castle in Brittany, wasting his last bit of strength in feverish fancies and ardent yearnings touching Isolde. Kurwenal has sent for her. Will she come? A shepherd tells of vain watches for the sight of a sail by playing a mournful melody on his pipe:-- [Musical excerpt]
