Norse mythology in the context of "Thor's Fight with the Giants"

The aegis (/ˈiːdʒɪs/ EE-jis; Ancient Greek: αἰγίς aigís), as stated in the Iliad, is a device carried by Athena and Zeus, variously interpreted as an animal skin or a shield and sometimes featuring the head of a Gorgon. There may be a connection with a deity named Aex, a daughter of Helios and a nurse of Zeus or alternatively a mistress of Zeus (Hyginus, Astronomica 2. 13).

The modern concept of doing something "under someone's aegis" means doing something under the protection of a powerful, knowledgeable, or benevolent source. The word aegis is identified with protection by a strong force with its roots in Greek mythology and adopted by the Romans; there are parallels in Norse mythology and in Egyptian mythology as well, where the Greek word aegis is applied by extension.

An elf (pl. elves) is a type of humanoid supernatural being in Germanic folklore. Elves appear especially in North Germanic mythology, being mentioned in the Icelandic Poetic Edda and the Prose Edda.

In medieval Germanic-speaking cultures, elves were thought of as beings with magical powers and supernatural beauty, ambivalent towards everyday people and capable of either helping or hindering them. Beliefs varied considerably over time and space and flourished in both pre-Christian and Christian cultures. The word elf is found throughout the Germanic languages. It seems originally to have meant 'white being'. However, reconstructing the early concept depends largely on texts written by Christians, in Old and Middle English, medieval German, and Old Norse. These associate elves variously with the gods of Norse mythology, with causing illness, with magic, and with beauty and seduction.

A troll is a being in Nordic folklore, including Norse mythology. In Old Norse sources, beings described as trolls dwell in isolated areas of rocks, mountains, or caves, live together in small family units, and are rarely helpful to human beings.

In later Scandinavian folklore, trolls became beings in their own right, where they live far from human habitation, are not Christianized, and are considered dangerous to human beings. Depending on the source, their appearance varies greatly; trolls may be ugly and slow-witted, or look and behave exactly like human beings, with no particularly grotesque characteristic about them.

An apple is the round, edible fruit of an apple tree (Malus spp.). Fruit trees of the orchard or domestic apple (Malus domestica), the most widely grown in the genus, are cultivated worldwide. The tree originated in Central Asia, where its wild ancestor, Malus sieversii, is still found. Apples have been grown for thousands of years in Eurasia before they were introduced to North America by European colonists. Apples have cultural significance in many mythologies (including Norse and Greek) and religions (such as Christianity in Europe).

Apples grown from seeds tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. For commercial purposes, including botanical evaluation, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the size of the resulting tree, allowing for easier harvesting.

The history of Greenland is a history of life under extreme Arctic conditions: currently, an ice sheet covers about eighty percent of the island, restricting human activity largely to the coasts. The first humans are thought to have arrived in Greenland around 2500 BCE. Their descendants most likely died out and were replaced and succeeded by several other human groups migrating from continental North America since then. There has been no evidence discovered that Greenland was known to Norsemen until the 9th century CE, when Norse Icelandic explorers settled on its southwestern coast. The ancestors of the Greenlandic Inuit who live there today appear to have migrated there later, around the year 1200, across the Nares Strait from northern Canada.

While Inuit survived in the icy world of the Little Ice Age, the early Norse settlements, known as the Eastern Settlement, along the southwestern coast disappeared, leaving Inuit as the only inhabitants of the island for several centuries. During this time, Denmark–Norway, apparently believing the Norse settlements had survived, continued to claim sovereignty over the island despite the lack of any contact between the Norsemen (specifically Icelanders) installed in Greenland and their Scandinavian brethren. In 1721, aspiring to become a colonial power, Denmark-Norway sent a missionary expedition to Greenland with the stated aim of reinstating Christianity among descendants of the Norse Greenlanders who may have converted back to paganism. When the missionaries found no descendants of the Norse Greenlanders, they baptised the Inuit they found living there instead. Denmark-Norway then developed trading colonies along the coast and imposed a trade monopoly and other colonial privileges on the area.

Snorri Sturluson (Old Norse: [ˈsnorːe ˈsturloˌson]; Icelandic: [ˈstnɔrːɪ ˈstʏ(r)tlʏˌsɔːn]; 1179 – 23 September 1241) was an Icelandic historian, poet, knight, and politician. He was elected twice as lawspeaker of the Icelandic parliament, the Althing. He is commonly thought to have authored or compiled portions of the Prose Edda, which is a major source for what is today known about Norse mythology and alliterative verse, and Heimskringla, a history of the Norse kings that begins with legendary material in Ynglinga saga and moves through to early medieval Scandinavian history. For stylistic and methodological reasons, Snorri is often taken to be the author of Egil's Saga. He was assassinated in 1241 by men claiming to be agents of the King of Norway.

In Norse mythology, Víðarr (Old Norse: [ˈwiːðɑrː], possibly "wide ruler", sometimes anglicized as Vidar /ˈviːdɑːr/, Vithar, Vidarr, and Vitharr) is a god among the Æsir associated with vengeance. Víðarr is described as the son of Odin and the jötunn Gríðr and is foretold to avenge his father's death by killing the wolf Fenrir at Ragnarök, a conflict he is described as surviving. Víðarr is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, the Prose Edda, written in the 13th century by Snorri Sturluson, and is interpreted as depicted with Fenrir on the Gosforth Cross. A number of theories surround the figure, including theories around potential ritual silence and a Proto-Indo-European basis.

Iceland was Christianized in the year 1000 AD, when Christianity was legally adopted as the official religion by decision of the Althing. In Icelandic, this event is known as the kristnitaka (literally, "the taking of Christianity").

The vast majority of the initial settlers of Iceland during the settlement of Iceland in the 9th and 10th centuries AD were pagan, worshipping the Æsir (the Norse gods). Beginning in 980, Iceland was visited by several Christian missionaries who had little success; but when Olaf Tryggvason (who had converted around 998) ascended to the Norwegian throne, there were many more converts, and the two rival religions soon divided the country and threatened civil war.

Old Norse religion, also known as Norse paganism, is a branch of Germanic religion which developed during the Proto-Norse period, when the North Germanic peoples separated into distinct branches. It was replaced by Christianity and forgotten during the Christianisation of Scandinavia. Scholars reconstruct aspects of North Germanic Religion by historical linguistics, archaeology, toponymy, and records left by North Germanic peoples, such as runic inscriptions in the Younger Futhark, a distinctly North Germanic extension of the runic alphabet. Numerous Old Norse works dated to the 13th-century record Norse mythology, a component of North Germanic religion.

Old Norse religion was polytheistic, entailing a belief in various gods and goddesses. These deities in Norse mythology were divided into two groups, the Æsir and the Vanir, who in some sources were said to have engaged in war until realizing that they were equally powerful. Among the most widespread deities were the gods Odin and Thor. This world was inhabited also by other mythological races, including jötnar, dwarfs, elves, and land-wights. Norse cosmology revolved around a world tree known as Yggdrasil, with various realms, such as Midgard, where humans live. These involved multiple afterlives, several of which were controlled by a particular deity.
