Deutsche Mythologie (Teutonic Mythology) is a seminal 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.
The structure of the Deutsche Mythologie is fairly encyclopaedic. The articles and chapters are discursive of philological, historical, folkloristic, and poetic aspects of the pre-Christian Germanic religions. The sources are varied epochally and geographically. In many instances, Grimm cites the North and West Germanic variants of a religious entity; thus the entry on Thor is titled 'Donar, Thunar (Thôrr)'. Older Germanic words, particularly those concerning ritual, are often compared to Latin equivalents, as evident in the table of contents.
