World tree

World tree is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand World tree rather than just read about it. In short: The world tree, also known as the cosmic tree, is a motif present in several religions and mythologies, particularly Indo-European, Siberian, and Native American religions. The world tree is represented as a colossal tree which supports the heavens, thereby connecting the heavens, the terrestrial world, and, through its roots, the underworld.

Key takeaways

  • World tree belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect World tree to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of World tree from memory before moving on to harder problems.

Reference excerpt

The world tree, also known as the cosmic tree, is a motif present in several religions and mythologies, particularly Indo-European, Siberian, and Native American religions. The world tree is represented as a colossal tree which supports the heavens, thereby connecting the heavens, the terrestrial world, and, through its roots, the underworld. It may also be strongly connected to the motif of the tree of life, but it is the source of wisdom of the ages. Specific world trees include Égig érő fa in Hungarian mythology, Ağaç Ana in Turkic mythology, Kenac' Car in Armenian mythology, Modun in Mongol mythology, Yggdrasil in Norse mythology, Irminsul in Germanic mythology, the oak in Slavic, Finnish and Baltic, Jianmu (Chinese: 建木; pinyin: jiànmù) in Chinese mythology, and in Hindu mythology the Ashvattha (a Ficus religiosa).

General description

Diffusion Scholarship states that many Eurasian mythologies share the motif of the "world tree", "cosmic tree", or "Eagle and Serpent Tree". More specifically, it shows up in "Haitian, Finnish, Lithuanian, Hungarian, Indian, Chinese, Japanese, Norse, Siberian and northern Asian Shamanic folklore".

Tripartite division of the world The World Tree is often identified with the Tree of Life, and also fulfills the role of an axis mundi, that is, a centre or axis of the world. It is also located at the center of the world and represents order and harmony of the cosmos. According to Loreta Senkute, each part of the tree corresponds to one of the three spheres of the world (treetops – heavens; trunk – middle world or earth; roots – underworld) and is also associated with a classical element (top part – fire; middle part – earth, soil, ground; bottom part – water). Its branches are said to reach the skies and its roots to connect the human or earthly world with an underworld or subterranean realm. Because of this, the tree was worshipped as a mediator between Heavens and Earth. On the treetops are located the luminaries (stars) and heavenly bodies, along with an eagle's nest; several species of birds perch among its branches; humans and animals of every kind live under its branches, and near the root is the dwelling place of snakes and every sort of reptiles.

Motifs The imagery of the World Tree is sometimes associated with conferring immortality, either by a fruit that grows on it or by a springsource located nearby. As George Lechler also pointed out, in some descriptions this "water of life" may also flow from the roots of the tree.

Zoological imagery According to Vladimir Toporov, animal species are commonly distributed along the parts of the tree: between its roots, figure "chthonic animals", such as snakes and frogs, but he also mentions aquatic animals such as otters, beavers, and fishes, as well as dragons; the middle part of the tree is reserved for hoofed animals such as deer or elk (sometimes bees), and on the topmost part perches the "principal" bird, or a pair of birds sat on either side of the tree crown. A bird perches atop its foliage, "often .... a winged mythical creature" that represents a heavenly realm. The eagle seems to be the most frequent bird, fulfilling the role of a creator or weather deity. Its antipode is a snake or serpentine creature that crawls between the tree roots, being a "symbol of the underworld".

Similar motifs The World Tree has also been compared to a World Pillar that appears in other traditions and functions as separator between the earth and the skies, upholding the latter. Another representation akin to the World Tree is a separate World Mountain. However, in some stories, the world tree is located atop the world mountain, in a combination of both motifs. A conflict between a serpentine creature and a giant bird (an eagle) occurs in Eurasian mythologies: a hero kills the serpent that menaces a nest of little birds, and their mother repays the favor – a motif comparativist Julien d'Huy dates to the Paleolithic. A parallel story is attested in the traditions of the indigenous peoples of the Americas, where the thunderbird is slotted into the role of the giant bird whose nest is menaced by a "snake-like water monster".

Relation to shamanism Romanian historian of religion, Mircea Eliade, in his monumental work Shamanism: Archaic Techniques of Ecstasy, suggested that the world tree was an important element in shamanistic worldview. Also, according to him, "the giant bird ... hatches shamans in the branches of the World Tree". Likewise, Roald Knutsen indicates the presence of the motif in Altaic shamanism. Representations of the world tree are reported to be portrayed in drums used in Siberian shamanistic practices. Some species of birds (eagle, raven, crane, loon, and lark) are revered as mediators between worlds and also connected to the imagery of the world tree. Another line of scholarship points to a "recurring theme" of the owl as the mediator to the upper realm, and its counterpart, the snake, as the mediator to the lower regions of the cosmos. Researcher Kristen Pearson mentions Northern Eurasian and Central Asian traditions wherein the World Tree is also associated with the horse and with deer antlers (which might resemble tree branches).

Possible origins Mircea Eliade proposed that the typical imagery of the world tree (bird at the top, snake at the root) "is presumably of Oriental origin". Likewise, Roald Knutsen indicates a possible origin of the motif in Central Asia and later diffusion into other regions and cultures.

Worked examples

Example 1 — a first encounter with World tree

Start with the simplest possible case. Write down what World tree claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to World tree before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about World tree ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of World tree

In research
World tree appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses World tree in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
World tree is common in secondary-school and first-year university syllabi. It links to neighbouring topics ATU 300-399, ATU 400-459, ATU 500-559, so understanding it makes those chapters shorter.
In everyday life
Look for World tree outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does World tree matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study World tree?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
