Elder Futhark in the context of "Futhorc"

The archaeology of Northern Europe studies the prehistory of Scandinavia and the adjacent North European Plain, roughly corresponding to the territories of modern Sweden, Norway, Denmark, Northern Germany, Poland, the Netherlands and Belgium.

The region entered the Mesolithic around the 7th millennium BC. The transition to the Neolithic is characterized by the Funnelbeaker culture in the 4th millennium BC. The Chalcolithic is marked by the arrival of the Corded Ware culture, possibly the first influence in the region of Indo-European expansion. The Nordic Bronze Age proper began roughly one millennium later, around 1500 BC. The end of the Bronze Age is characterized by cultural contact with the Central European La Tène culture (Celts), contributing to the development of the Iron Age by the 4th century BC, presumably the locus of Common Germanic culture. Northern Europe enters the protohistorical period in the early centuries AD, with the adoption of writing and ethnographic accounts by Roman authors.

Æsir (Old Norse; singular: áss) or ēse (Old English; singular: ōs) are gods in Germanic paganism. In Old Nordic religion and mythology, the precise meaning of the term "Æsir" is debated, as it can refer either to the gods in general or specifically to one of the main families of gods, in contrast to the Vanir, with whom the Æsir waged war, ultimately leading to a joining of the families. The term can further be applied to local gods that were believed to live in specific features in the landscape – such as fells. The Old English medical text Wið færstice refers to the Ēse, along with elves, as harmful beings that could cause a stabbing pain, although exactly how they were conceived of by the author of the text is unclear.

Áss and its cognate forms feature in many Germanic names, such as Oswald and Ásmundr, and in some place-names in Norway and Sweden. The Æsir further likely give their name to the A-rune, attested in the Elder Futhark, Anglo-Saxon Futhorc and Younger Futhark.

Proto-Norse was an Indo-European language spoken in Scandinavia that is thought to have evolved as a northern dialect of Proto-Germanic in the first centuries CE. It is the earliest stage of a characteristically North Germanic language, and the language attested in the oldest Scandinavian Elder Futhark inscriptions, spoken from around the 2nd to the 8th centuries CE (corresponding to the late Roman Iron Age and the Germanic Iron Age). It evolved into the dialects of Old Norse at the beginning of the Viking Age around 800 CE, which later themselves evolved into the modern North Germanic languages (Faroese, Icelandic, the Continental Scandinavian languages, and their dialects).

Anglo-Saxon runes or Anglo-Frisian runes are runes that were used by the Anglo-Saxons and Medieval Frisians (collectively called Anglo-Frisians) as an alphabet in their native writing system, recording both Old English and Old Frisian (Old English: ᚱᚢᚾᚪ, romanized: rūna, lit. 'rune'). Today, the characters are known collectively as the futhorc (ᚠᚢᚦᚩᚱᚳ, fuþorc) from the first six runes and their sound values. The futhorc was a development from the older co-Germanic 24-character runic alphabet, known today as Elder Futhark, expanding to 28 characters in its older form and up to 34 characters in its younger form. In contemporary Scandinavia, the Elder Futhark developed into a shorter 16-character alphabet, today simply called Younger Futhark.

Use of the Anglo-Frisian runes is likely to have started in the 5th century onward and they continued to see use into the High Middle Ages. By the 8th century, they were eventually overtaken by the Old English Latin alphabet introduced to Anglo-Saxon England by missionaries at the end of the 6th century. Futhorc runes were no longer in common use by the 11th century, but MS Oxford St John's College 17 indicates that fairly accurate understanding of them persisted into at least the 12th century.

Ansuz is the conventional name given to the a-rune of the Elder Futhark, ᚨ.The name is based on Proto-Germanic *ansuz, denoting a deity belonging to the principal pantheon in Germanic paganism.

The shape of the rune is likely from Neo-Etruscan a (), like Latin A ultimately from Phoenician aleph.

The sequence alu (ᚨᛚᚢ) is found in numerous Elder Futhark runic inscriptions of Germanic Iron Age Scandinavia (and more rarely in early Anglo-Saxon England) between the 3rd and the 8th century. The word usually appears either alone (such as on the Elgesem runestone) or as part of an apparent formula (such as on the Lindholm "amulet" (DR 261) from Scania, Sweden). The symbols represent the runes Ansuz, Laguz, and Uruz. The origin and meaning of the word are matters of dispute, though a general agreement exists among scholars that the word represents an instance of historical runic magic or is a metaphor (or metonym) for it. It is the most common of the early runic charm words.

The word disappears from runic inscriptions shortly after the Migration Period, even before the Christianization of Scandinavia.It may have lived on beyond this period with an increasing association with ale, appearing in stanzas 7 and 19 of the Old Norse poem Sigrdrífumál, compiled in the 13th century Poetic Edda, where knowledge of invocative "ale runes" (Old Norse ölrúnar) is imparted by the Valkyrie Sigrdrífa. Theories have been suggested that the unique term ealuscerwen (possibly "pouring away of alu"), used to describe grief or terror in the epic poem Beowulf, recorded around the 9th to 11th century, may be directly related.
