Germanic religion and mythology

Germanic religion and mythology:

complex of stories, lore, and beliefs about the gods and the nature of the cosmos developed by the Germanic-speaking peoples before their conversion to Christianity.
Germanic culture extended, at various times, from the Black Sea to Greenland, or even the North American continent. Germanic religion played an important role in shaping the civilization of Europe. But since the Germanic peoples of the Continent and of England were converted to Christianity in comparatively early times, it is not surprising that less is known about the gods whom they used to worship and the forms of their religious cults than about those of Scandinavia, where Germanic religion survived until relatively late in the Middle Ages.

Classical and early medieval sources

The works of classical authors, written mostly in Latin and occasionally in Greek, throw some light on the religion of Germanic peoples; however, their interest in the religious practices of Germanic tribes remains limited to its direct relevance to their narrative, as when Strabo describes the gory sacrifice of Roman prisoners by the Cimbri at the end of the 2nd century bc.
For all his knowledge of the Celts, Caesar had no more than a superficial knowledge of Germans. He made some judicious observations in Commentarii de bello Gallico about their social and political organization, but his remarks on their religion were rather perfunctory. Contrasting Germans with the Celts of Gaul, Caesar claimed that the Germans had no druids (i.e., organized priesthood), nor zeal for sacrifice, and counted as gods only the Sun, the fire god (Vulcan or Vulcanus), and the Moon. His limited information accounts for Caesar’s assumption of the poverty of the Germanic religion and the partial inaccuracy and incompleteness of his statement.
Tacitus, on the contrary, provided a lucid picture of customs and religious practices of continental Germanic tribes in his Germania, written c. ad 98. He describes some of their rituals and occasionally names a god or goddess. While Tacitus presumably never visited Germany, his information was partly based on direct sources; he also used older works, now lost.
