Proto-Germanic folklore in the context of "Folk belief"

Germanic paganism or Germanic religion was the traditional, culturally significant religion of the Germanic peoples. With a chronological range of at least one thousand years in an area covering Scandinavia, the British Isles, modern Germany, the Netherlands, and at times other parts of Europe, the beliefs and practices of Germanic paganism varied. Scholars typically assume some degree of continuity between the beliefs and practices of the Roman era and those found in Norse paganism, as well as between Germanic religion and reconstructed Indo-European religion and post-conversion folklore, though the precise degree and details of this continuity are subjects of debate. Germanic religion was influenced by neighboring cultures, including that of the Celts, the Romans, and, later, by Christianity. Very few sources exist that were written by pagan adherents themselves; instead, most were written by outsiders and can thus present problems for reconstructing authentic Germanic beliefs and practices.

Some basic aspects of Germanic belief can be reconstructed, including the existence of one or more origin myths, the existence of a myth of the end of the world, a general belief in the inhabited world being a "middle-earth", as well as some aspects of belief in fate and the afterlife. The Germanic peoples believed in a multitude of gods, and in other supernatural beings such as jötnar (often glossed as giants), dwarfs, elves, and dragons. Roman-era sources, using Roman names, mention several important male gods, as well as several goddesses such as Nerthus and the matronae. Early medieval sources identify a pantheon consisting of the gods *Wodanaz (Odin), *Thunraz (Thor), *Tiwaz (Tyr), and *Frijjō (Frigg), as well as numerous other gods, many of whom are only attested from Norse sources (see Proto-Germanic folklore).

Norse, Nordic, or Scandinavian mythology, is the body of myths belonging to the North Germanic peoples, stemming from Old Norse religion and continuing after the Christianization of Scandinavia as the Nordic folklore of the modern period. The northernmost extension of Germanic mythology and stemming from Proto-Germanic folklore, Norse mythology consists of tales of various deities, beings, and heroes derived from numerous sources from both before and after the pagan period, including medieval manuscripts, archaeological representations, and folk tradition. The source texts mention numerous gods such as the thunder-god Thor, the raven-flanked god Odin, the goddess Freyja, and numerous other deities.

Most of the surviving mythology centers on the plights of the gods and their interaction with several other beings, such as humanity and the jötnar, beings who may be friends, lovers, foes, or family members of the gods. The cosmos in Norse mythology consists of Nine Worlds that flank a central sacred tree, Yggdrasil. Units of time and elements of the cosmology are personified as deities or beings. Various forms of a creation myth are recounted, where the world is created from the flesh of the primordial being Ymir, and the first two humans are Ask and Embla. These worlds are foretold to be reborn after the events of Ragnarök when an immense battle occurs between the gods and their enemies, and the world is enveloped in flames, only to be reborn anew. There the surviving gods will meet, and the land will be fertile and green, and two humans will repopulate the world.
