Duchess monologue (Act 3) — The Death of Wallenstein

Thou wilt share An easier, calmer lot, my child! We, too, I and thy father, witnessed happy days. Still think I with delight of those first years, When he was making progress with glad effort, When his ambition was a genial fire, Not that consuming flame which now it is. The emperor loved him, trusted him; and all He undertook could not but be successful. But since that ill-starred day at Regensburg, Which plunged him headlong from his dignity, A gloomy, uncompanionable spirit, Unsteady and suspicious, has possessed him. His quiet mind forsook him, and no longer Did he yield up himself in joy and faith To his old luck and individual power; But thenceforth turned his heart and best affections All to those cloudy sciences which never Have yet made happy him who followed them.
