With his own literary production and his literary scholarship and criticism, Ludwig Tieck (1773‑1853) was a determining figure in literature and cultural activity around 1800 and in the epochal situation after the (Goethean) ‘art period’. This reference work presents Tieck’s life and times, locates his work in its aesthetic tradition and describes his poetics and commitment as a literary critic, editor and literary scholar. Individual texts are analysed in detail, within the context of his complete work and within the context of their time. Another strong focus lies on the impact and reception of Tieck’s work. The articles are complemented by a complete bibliography of research.
