In this excerpt from Lord Byron's "She Walks in Beauty," which two sets of lines show that Byron's subject is rich in kindness and grace? She walks in beauty, like the night Of cloudless climes and starry skies; And all that’s best of dark and bright Meet in her aspect and her eyes; Thus mellowed to that tender light Which heaven to gaudy day denies. One shade the more, one ray the less, Had half impaired the nameless grace Which waves in every raven tress, Or softly lightens o’er her face; Where thoughts serenely sweet express, How pure, how dear their dwelling-place.
