Then as the Ring Motive resounds like a shout of malicious triumph (expressive of Alberich's malignant joy at his possession of power), there is seen a subterranean cavern, apparently of illimitable depth, from which narrow shafts lead in all directions.

Scene III. Alberich enters from a side cleft dragging after him the shrieking Mime. The latter lets fall a helmet which Alberich at once seizes. It is the Tarnhelmet, made of Rhinegold, the wearing of which enables the wearer to become invisible or assume any shape. As Alberich closely examines the helmet the Motive of the Tarnhelmet is heard.

It is mysterious, uncanny. To test its power Alberich puts it on and changes into a column of vapour. He asks Mime if he is visible, and when Mime answers in the negative Alberich cries out shrilly, "Then feel me instead," at the same time making poor Mime writhe under the blows of a visible scourge. Alberich then departs—still in the form of a vaporous column—to announce to the Nibelungs that they are henceforth his slavish subjects. Mime cowers down with fear and pain.

Wotan and Loge enter from one of the upper shafts. Mime tells them how Alberich has become all-powerful through the ring and the Tarnhelmet made of the Rhinegold. Then Alberich, who has taken off the Tarnhelmet and hung it from his girdle, is seen in the distance, driving a crowd of Nibelungs before him from the caves below. They are laden with gold and silver, which he forces them to pile up in one place and so form a hoard. He suddenly perceives Wotan and Loge. After abusing Mime for permitting strangers to enter Nibelheim, he commands the Nibelungs to descend again into the cavern in search of new treasure for him. They hesitate. You hear the Ring Motive. Alberich draws the ring from his finger, stretches it threateningly toward the Nibelungs, and commands them to obey their master.

They disperse in headlong flight, with Mime, into the cavernous recesses. Alberich looks with mistrust upon Wotan and Loge. Wotan tells him they have heard report of his wealth and power and have come to ascertain if it is true. The Nibelung points to the hoard. He boasts that the whole world will come under his sway (Ring Motive), that the gods who now laugh and love in the enjoyment of youth and beauty will become subject to him (Freia Motive); for he has abjured love (Motive of Renunciation). Hence, even the gods in Walhalla shall dread him (Walhalla Motive) and he bids them beware of the time when the night-begotten host of the Nibelungs shall rise from Nibelheim into the realm of daylight. (Rhinegold Motive followed by Walhalla Motive, for it is through the power gained by the Rhinegold that Alberich hopes to possess himself of Walhalla.) Loge cunningly flatters Alberich, and when the latter tells him of the Tarnhelmet, feigns disbelief of Alberich's statements. Alberich, to prove their truth, puts on the helmet and transforms himself into a huge serpent. The Serpent Motive expresses the windings and writhings of the monster. The serpent vanishes and Alberich reappears. When Loge doubts if Alberich can transform himself into something very small, the Nibelung changes into a toad. Now is Loge's chance. He calls Wotan to set his foot on the toad. As Wotan does so, Loge puts his hand to its head and seizes the Tarnhelmet. Alberich is seen writhing under Wotan's foot. Loge binds Alberich; both seize him, drag him to the shaft from which they descended and disappear ascending.

The scene changes in the reverse direction to that in which it changed when Wotan and Loge were descending to Nibelheim. The orchestra accompanies the change of scene. The Ring Motive dies away from crashing fortissimo to piano, to be succeeded by the dark Motive of Renunciation. Then is heard the clangour of the Nibelung smithies. The Giant, Walhalla, Loge, and Servitude Motives follow the last with crushing force as Wotan and Loge emerge from the cleft, dragging the pinioned Alberich with them. His lease of power was brief. He is again in a condition of servitude.

Scene IV. A pale mist still veils the prospect as at the end of the second scene. Loge and Wotan place Alberich on the ground and Loge dances around the pinioned Nibelung, mockingly snapping his fingers at the prisoner. Wotan joins Loge in his mockery of Alberich. The Nibelung asks what he must give for his freedom. "Your hoard and your glittering gold," is Wotan's answer. Alberich assents to the ransom and Loge frees the gnome's right hand. Alberich raises the ring to his lips and murmurs a secret behest. The Nibelungs emerge from the cleft and heap up the hoard. Then, as Alberich stretches out the ring toward them, they rush in terror toward the cleft, into which they disappear. Alberich now asks for his freedom, but Loge throws the Tarnhelmet on to the heap. Wotan demands that Alberich also give up the ring. At these words dismay and terror are depicted on the Nibelung's face. He had hoped to save the ring, but in vain. Wotan tears it from the gnome's finger. Then Alberich, impelled by hate and rage, curses the ring. The Motive of the Curse:
