Brünnhilde’s eight warrior sisters—who have gathered on their mountaintop bearing slain heroes to Valhalla. They are surprised to see Brünnhilde arrive with a woman, Sieglinde. When they hear she is fleeing Wotan’s wrath, they are afraid to hide her. Sieglinde is numb with despair until Brünnhilde tells her she bears Siegmund’s child. Now eager to be saved, she takes the pieces of the sword from Brünnhilde, thanks her, and rushes off into the forest to hide from Wotan. When the god appears, he sentences Brünnhilde to become a mortal woman, silencing her sisters’ objections by threatening to do the same to them. Left alone with her father, Brünnhilde pleads that in disobeying his orders she was really doing what he wished. Wotan will not give in: she must lie in sleep, a prize for any man who finds her. She asks to be surrounded in sleep by a wall of fire that only the bravest hero can pierce. Both sense this hero must be the child that Sieglinde will bear. Sadly renouncing his daughter (“Leb’ wohl, du kühnes, herrliches Kind”), Wotan kisses Brünnhilde’s eyes with sleep and mortality before summoning Loge, the god of fire, to encircle the rock. As flames spring up, the departing Wotan invokes a spell defying anyone who fears his spear to brave the flames.
