Runic inscriptions in the context of "Alu (runic)"

Old Norse was a North Germanic language spoken in Scandinavia and in Norse settlements during the Viking Age and the early Middle Ages (approximately the 8th–14th centuries). It is the conventional term for the medieval West and East Scandinavian dialects (often labelled Old West Norse and Old East Norse) that developed from Proto-Norse and later evolved into the modern North Germanic languages, including Icelandic, Faroese, Norwegian, Danish, and Swedish.

Old Norse is attested in runic inscriptions (written in the Younger Futhark) and in numerous medieval manuscripts written with the Latin alphabet; its literary corpus includes the Poetic Edda, the Prose Edda, the Icelandic sagas, skaldic verse, law codes, and religious texts. Contact between Old Norse speakers and other languages — particularly Old English and the Celtic languages — left a substantial legacy of loanwords and toponyms; many common English words such as egg, knife, sky, and window derive from Old Norse.

In Scandinavian prehistory, sometimes specifically Swedish prehistory, the Vendel Period, or Vendel Age (Swedish: Vendeltiden; c. 540–790 AD) appears between the Migration Period and the Viking Age. The name is taken from the rich boat inhumation cemetery at Vendel parish church, Uppland. Unlike the preceding and succeeding eras, the Vendel Period left very few precious metal artifacts or runic inscriptions. Instead, it is extremely rich in animal art on copper-alloy objects. It is also known for guldgubbar, tiny embossed gold foil images, and elaborate helmets with embossed decoration similar to the one found at Sutton Hoo in England.

During the period, Swedish expeditions began to explore the waterways of territories which later became Russia, Ukraine, and Belarus. The Elder Futhark writing system was abandoned in favor of the Younger Futhark, virtually simultaneously over the whole of Scandinavia. Some runestones survive, most notably those at Rök and Sparlösa, both from c. 800. Other written sources are few and hard to interpret: a few Icelandic sagas, the tale of Beowulf, and accounts from some southern European writers. Earlier Swedish historians tried to make use of these to create a coherent history, but this effort has largely been abandoned, and the period is now mostly studied by archaeologists.

In Norse mythology, a valkyrie (/ˈvælkɪri/ VAL-kirr-ee or /vælˈkɪəri/ val-KEER-ee; from Old Norse: valkyrja, lit. 'chooser of the slain') is one of a host of female figures who guide souls of the dead to the god Odin's hall Valhalla. There, the deceased warriors become einherjar ('single fighters' or 'once fighters'). When the einherjar are not preparing for the cataclysmic events of Ragnarök, the valkyries bear them mead. Valkyries also appear as lovers of heroes and other mortals, where they are sometimes described as the daughters of royalty, sometimes accompanied by ravens and sometimes connected to swans or horses.

Valkyries are attested in the Poetic Edda (a book of poems compiled in the 13th century from earlier traditional sources), the Prose Edda, the Heimskringla (both by Snorri Sturluson) and the Njáls saga (one of the Sagas of Icelanders), all written—or compiled—in the 13th century. They appear throughout the poetry of skalds, in a 14th-century charm, and in various runic inscriptions.

Runes are the letters in a set of related alphabets, known as runic rows, runic alphabets or futharks (also, see futhark vs runic alphabet), native to the Germanic peoples. Runes were primarily used to represent a sound value (a phoneme) but they were also used to represent the concepts after which they are named (ideographic runes). Runology is the academic study of the runic alphabets, runic inscriptions, runestones, and their history. Runology forms a specialised branch of Germanic philology.

The earliest secure runic inscriptions date from at latest AD 150, with a possible earlier inscription dating to AD 50 and Tacitus's possible description of rune use from around AD 98. The Hole Runestone dates from between BC 50 and AD 275. Runes were generally replaced by the Latin alphabet as the cultures that had used runes underwent Christianisation, by approximately AD 700 in central Europe and 1100 in northern Europe. However, the use of runes persisted for specialized purposes beyond this period. Up until the early 20th century, runes were still used in rural Sweden for decorative purposes in Dalarna and on runic calendars.
