Melancholic, although often sardonic, mixtures of emoitions-foreboding, aloneness, regret, and a dark sense of lost destiny and ill-used passions-are woven throughout Byron's most autobiographical poems, especially Childe Harold's Pilgrimage, Lara, and Manfred. Perturbed and constant motion, coupled with a brooding awareness of life's impermanence, also mark the transient and often bleak nature of Byron's work.
