Context paragraphs:
Svinfylking: The Svinfylking, Old Norse for 'Swine Array' or 'Boar Snout', was a version of the wedge formation used in Iron Age Scandinavia then by the Vikings, and by the Germanic peoples during the Germanic Iron Age where it was known as the "Schweinskopf" or 'Swine's Head'.  Its invention was attributed to the god Odin.

Picture stone: A picture stone, image stone or figure stone is an ornate slab of stone, usually limestone, which was raised in Germanic Iron Age or Viking Age Scandinavia, and in the greatest number on Gotland.  More than four hundred picture stones are known today.  All of the stones were probably erected as memorial stones, but only rarely beside graves.  Some of them have been positioned where many people could see them at bridges and on roads.

Alu (runic): The sequence alu () 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.

House of Monpezat: The House of Laborde de Monpezat (] ) is a French family, known since the seventeenth century, associated with the Danish Royal Family by marriage after 1967, when Henri de Laborde de Monpezat wed Princess Margrethe of Denmark, heir presumptive of the ruling House of Glücksburg.  In the event of ascension to the Danish throne of their son or male-line descendant, the main branch of the Danish Royal Family will belong patrilineally to the "Laborde de Monpezat" lineage.  However, it is unclear which name the royal family will use in this event.

House of Knýtlinga: The Danish House of Knýtlinga (English: "House of Cnut's Descendants") was a ruling royal house in Middle Age Scandinavia and England.  Its most famous king was Cnut the Great, who gave his name to this dynasty.  Other notable members were Cnut's father Sweyn Forkbeard, grandfather Harald Bluetooth, and sons Harthacnut, Harold Harefoot, and Svein Knutsson.  It has also been called the House of Canute, the House of Denmark, the House of Gorm, or the Jelling Dynasty.

Viking Childhood: In Viking Age Scandinavia, boys were legally considered to be adults at age 12.  But before they reached adulthood, they had a childhood spent learning the skills they would need to be successful.  Viking children were primarily raised by their mothers, although sometimes Viking boys lived with another family for a period of time as a foster-child.  This was meant to forge bonds between the two families and entitled the boy to help from his foster family, as well as his birth family.  It also bound him to them and they often remained close through the life of the boy.

Atgeir: An atgeir, sometimes called a "mail-piercer" or "hewing-spear," was a type of polearm in use in Viking Age Scandinavia and Norse colonies in the British Isles and Iceland.  It is usually translated in English as "halberd", but most likely closer resembled a bill or glaive during the Viking age.  Another view is that the term had no association with a specific weapon until it is used as an anachronism in saga literature to lend weight to accounts of special weapons.  Later the word was used for typical European halberds, and even later multipurpose staves with spearheads were called "atgeirsstafir".

The Viking Way (book): The Viking Way: Religion and War in Late Iron Age Scandinavia is an archaeological study of Norse paganism in Late Iron Age Scandinavia.  It was written by the English archaeologist Neil Price, then a professor at the University of Aberdeen, and first published by the Department of Archaeology and Ancient History at Uppsala University in 2002.  A revised second edition is due to be published in 2017 by Oxbow Books.

Gunhilda of Denmark: Gunhilda of Denmark ( 1020 – 18 July 1038), a member of the House of Knýtlinga, was Queen consort of Germany by her marriage with King Henry III of the Salian dynasty from 1036 until her death.

Iron Age Scandinavia: Iron Age Scandinavia (or Nordic Iron Age) refers to the Iron Age, as it unfolded in Scandinavia.
