Alu (runic) in the context of "Ansuz (rune)"

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).

There is some evidence that, in addition to being a writing system, runes historically served purposes of magic. This is the case from the earliest epigraphic evidence of the Roman to the Germanic Iron Age, with non-linguistic inscriptions and the alu word. An erilaz appears to have been a person versed in runes, including their magic applications.

In medieval sources, notably the Poetic Edda, the Sigrdrífumál mentions "victory runes" to be carved on a sword, "some on the grasp and some on the inlay, and name Tyr twice."

A bracteate (from the Latin bractea, a thin piece of metal) is a flat, thin, single-sided gold medal worn as jewelry that was produced in Northern Europe predominantly during the Migration Period of the Germanic Iron Age (including the Vendel era in Sweden). Bracteate coins are also known from the medieval kingdoms around the Bay of Bengal, such as Harikela and Mon city-states. The term is also used for thin discs, especially in gold, to be sewn onto clothing in the ancient world, as found for example in the ancient Persian Oxus treasure, and also later silver coins produced in central Europe during the Early Middle Ages.

Alruna (Old Norse Ǫlrún, Old High German Ailrun, Modern German Alruna, Alraune) is a Germanic female personal name, from Proto Germanic *aliruna (or possibly *agilruna), which is formed from runa "secret, rune" and a debated prefix that may be ali-, agil-, or alu-.

In German, Alruna was also used as a short form of Adelruna, a different name with a first element *athal- "noble".
