For here his foot hath trod; these walls have echoed to
the voice I love; these chains so cold and heavy I more gladly wear than
e'en the costly gems once clasped upon these arms, for they were his.
Here his sad tears fell perchance for his captivity; but I can smile and
bless the hour when I could win thy freedom, Adrian, with my poor
liberty. Hark--they come. Is it to claim the vow I made to yield my
bosom to the dagger meant for his? I am ready. [_Enter_ Don Felix.]
Alone, my lord; methought it were too sad a task for thee to take my
life. Well, be it so; you claim my vow. I can die still blessing thee,
my Adrian [_kneels before_ Don Felix].

Don Felix. Rise, Nina; ah, kneel not to me, nor think this hand could
take the life it prizes more than happiness or honor. I came not here to
harm thee; Heaven forbid! I came once more to offer thee my heart, my
home, and all the boundless love you have so scorned. Thy husband hath
deserted thee; no ties too fast to sever bind thee to him. Thou art
alone, a captive, and I alone can free thee. Think of the love I bear

Nina. Where is thy boasted honor now? Where the solemn vow thou didst
make me that my lonely cell should be as sacred to thee as my palace

affection never binds such chains as these, nor causes bitter tears like
mine to flow. Rather suffer death than cherish in my heart one tender
thought of thee. Thou hast my answer, now leave me.

Don Felix. Not yet, proud captive. I have sought to win thee gently; but
now, beware. Think not to escape me, thou shalt feel how deep a
vengeance I can bring on thee and him thou lovest. Thou shalt suffer all
the sorrow I can inflict,--shalt know thy proud lord forsaken and in
danger when a word from me can save, and _that_ word I will not speak.
All the grief and pain and hatred that my jealous heart can give will I
heap upon his head, and thus through him I will revenge myself on thee.

Nina. Thou canst not harm him, he is safe and free. Do thy worst, I care
not what fate thou hast for me, a fearless hand soon finds a way to free
a soul from sorrow and captivity. This heart thou canst not reach. It
fears thee not.

Don Felix. Can I not make thee tremble, haughty woman? I love thee
still, and I will win thee. I go to work thee sorrow; and when next
