Norna. Ha, that's well! Thou wilt join me, for I have made a vow to rest not till that proud, sinful lord hath well atoned for this deep crime. Spirits shall haunt him, and the darkest phantoms that my art can raise shall scare his soul. Wilt thou join me in my work? Louis. I will,--but stay! thou hast spoken of spirits. Dread sorceress, is it in thy power to call them up? Norna. It is. Wilt see my skill. Stand back while I call up a phantom which thou canst not doubt. [Louis _retires within the cave._ Norna _weaves a spell above her caldron._ Norna. O spirit, from thy quiet tomb, I bid thee hither through the gloom, In winding-sheet, with bloody brow, Rise up and hear our solemn vow. I bid thee, with my magic power, Tell the dark secret of that hour When cruel hands, with blood and strife, Closed the sad dream of thy young life. Hither--appear before our eyes. Pale spirit, I command thee _rise_. [_Spirit of_ Theresa _rises._ Shadowy spirit, I charge thee well, By my mystic art's most potent spell, To haunt throughout his sinful life, The mortal who once called thee wife. At midnight hour glide round his bed, And lay thy pale hand on his head. Whisper wild words in his sleeping ear, And chill his heart with a deadly fear. Rise at his side in his gayest hour, And his guilty soul shall feel thy power. Stand thou before him in day and night, And cast o'er his life a darksome blight; For with all his power and sin and pride, He shall ne'er forget his murdered bride. Pale, shadowy form, wilt thou obey? [_The spirit bows its head._ To thy ghostly work away--away! [_The spirit vanishes._ The spell is o'er, the vow is won, And, sinful heart, _thy_ curse begun. [_Re-enter_ Louis. Louis. 'Tis enough! I own thy power, and by the spirit of my murdered sister I have looked upon, I swear to aid thee in thy dark work. Norna. 'Tis well; and I will use my power to guard thee from the danger that surrounds thee. And now, farewell. Remember,--thou hast sworn. [_Exit_ Louis. CURTAIN. SCENE THIRD. [_Another part of the wood. Enter_ Rodolpho.] Rod. They told me that old Norna's cave was 'mong these rocks, and yet I find it not. By her I hope to learn where young Count Louis is concealed. Once in my power, he shall not escape to whisper tales of evil deeds against me. Stay! some one comes. I'll ask my way. [_Enter_ Louis _masked._ Ho, stand, good sir. Canst guide me to the cell of Norna, the old sorceress?
