Concept
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." In the early modern period and modern history, related folklore and superstition is recorded in the form of the Icelandic magical staves. In the early 20th century, Germanic mysticism coined new forms of "runic magic", some of which were continued or developed further by contemporary adherents of Germanic Neopaganism. Modern systems of runic divination are based on Hermeticism, classical Occultism, and the I Ching. Historically it is known that the Germanic peoples used various forms of divination and means of reading omens. Tacitus (Germania 10) gives a detailed account (98AD): They attach the highest importance to the taking of auspices and casting lots. Their usual procedure with the lot is simple. They cut off a branch from a nut-bearing tree and slice it into strips these they mark with different signs and throw them at random onto a white cloth. Then the state's priest, if it is an official consultation, or the father of the family, in a private one, offers prayer to the gods and looking up towards heaven picks up three strips, one at a time, and, according to which sign they have previously been marked with, makes his interpretation. If the lots forbid an undertaking, there is no deliberation that day about the matter in question. If they allow it, further confirmation is required by taking auspices. It is often debated whether "signs" refers specifically to runes or to other marks; both interpretations are plausible and Tacitus does not give enough detail for a definite decision to be made.
