In the second act we return to the hall of Gibich, where Hagen, in the last hours of that night, still sits, his spear in his hand, and his shield beside him. At his knees crouches a dwarfish spectre, his father Alberic, still full of his old grievances against Wotan, and urging his son in his dreams to win back the ring for him. This Hagen swears to do; and as the apparition of his father vanishes, the sun rises and Siegfried suddenly comes from the river bank tucking into his belt the Tarnhelm, which has transported him from the mountain like the enchanted carpet of the Arabian tales. He describes his adventures to Gutrune until Gunther's boat is seen approaching, when Hagen seizes a cowhorn and calls the tribesmen to welcome their chief and his bride. It is most exhilarating, this colloquy with the startled and hastily armed clan, ending with a thundering chorus, the drums marking the time with mighty pulses from dominant to tonic, much as Rossini would have made them do if he had been a pupil of Beethoven's. A terrible scene follows. Gunther leads his captive bride straight into the presence of Siegfried, whom she claims as her husband by the ring, which she is astonished to see on his finger: Gunther, as she supposes, having torn it from her the night before. Turning on Gunther, she says "Since you took that ring from me, and married me with it, tell him of your right to it; and make him give it back to you." Gunther stammers, "The ring! I gave him no ring--er--do you know him?" The rejoinder is obvious. "Then where are you hiding the ring that you had from me?" Gunther's confusion enlightens her; and she calls Siegfried trickster and thief to his face. In vain he declares that he got the ring from no woman, but from a dragon whom he slew; for he is manifestly puzzled; and she, seizing her opportunity, accuses him before the clan of having played Gunther false with her.
