Original Poetry by Victor and Cazire was a poetry collection written by Percy Bysshe Shelley and his sister Elizabeth. Shelley contributed seven lyrical poems, four Gothic poems, and the political poem "The Irishman's Song". Elizabeth wrote three lyrical poems and two verse epistles. The collection included the early poems "Revenge", "Ghasta, Or, The Avenging Demon!!!", "Song: Sorrow", and "Song: Despair". The epigraph was from the "Lay of the Last Minstrel" by Sir Walter Scott: "Call it not vain:— they do not err, Who say, that, when the poet dies, Mute Nature mourns her worshipper."
