Deutsche Mythologie (German: [ˈdɔʏtʃə mytoloˈɡiː], Teutonic Mythology) is a treatise on Germanic mythology by Jacob Grimm. First published in Germany in 1835, the work is an exhaustive treatment of the subject, tracing the mythology and beliefs of the ancient Germanic peoples from their earliest attestations to their survivals in modern traditions, folktales and popular expressions.
