At the turn of the 19th century vampire poetry began to appear in English like John Stag's "The Vampyre" (1810) and Sir Byron's The Giaour (1813). The story of the first prose vampire published in English is considered John Polydree's "The Vampyre" (1819), a mysterious aristocrat who disappointed the young woman as Lord mainly lost Luthven . These works and other works influenced the tracking materials of the stage.
