A sun cross, solar cross, or wheel cross is a solar symbol consisting of an equilateral cross inside a circle. The design is frequently found in the symbolism of prehistoric cultures, particularly during the Neolithic to Bronze Age periods of European prehistory. The symbol's ubiquity and apparent importance in prehistoric religion have given rise to its interpretation as a solar symbol, whence the modern English term "sun cross". The same symbol is in use as a modern astronomical symbol representing the Earth rather than the Sun.
Interpretation as solar symbol
The interpretation of the simple equilateral cross as a solar symbol in Bronze Age religion was widespread in 19th-century scholarship. The cross-in-a-circle was interpreted as a solar symbol derived from the interpretation of the disc of the Sun as the wheel of the chariot of the Sun god. Wieseler postulated an Gothic rune hvel representing the solar deity by the "wheel" symbol of a cross-in-a-circle, reflected by the Gothic letterhwair. The English term "Sun-Cross", on the other hand, is comparatively recent, apparently loaned from German Sonnenkreuz and used in the 1955 translation of Rudolf Koch's Book of Signs. The German term Sonnenkreuz was used in 19th-century scholarly literature of any cross symbol interpreted as a solar symbol, an equilateral cross either with or without a circle, or an oblique cross. Sonnenkreuz was used of the flag design of the Paneuropean Union in the 1920s. In the 1930s, a version of the symbol with broken arms was popular as a link between Christianity and Germanic paganism in the völkischGerman Faith Movement.
Archaeological record
Bronze Age
In the prehistoric religion of Bronze Age Europe, crosses in circles appear frequently on artifacts identified as cult items, for example the "miniature standard" with an amber inlay that shows a cross shape when held against the light, dating to the Nordic Bronze Age, held at the National Museum of Denmark, Copenhagen. The Bronze Age symbol has also been connected with the spoked chariot wheel, which at the time was four-spoked. In the context of a culture that celebrated the sun chariot, it may thus have had a "solar" connotation.
Modern culture
Astronomy
The same symbol represents the Earth in astronomical symbols, while the Sun is represented by a circle with a center point.
The Sassanian Empire in Persia used a similar solar cross on their banner, called the Derafsh Kaviani symbol. The Norwegianfascist party Nasjonal Samling used a golden sun cross on a red background as an official symbol from 1933 to 1945. The cross with the circle was attached to Olaf II of Norway, patron saint of Norway, and the colors were the coat of arms of Norway. The Paneuropean Union, a European unification movement, uses this symbol as central element of its flag. A square cross interlocking with or surrounded by a circle is one of the most popular symbols used by individuals and organisations to represent white nationalism, white supremacy, Neo-Nazism, and white pride; it is used as the logo for white nationalist website Stormfront. This stems from the use of a circled cross by Norwegian Nazis during World War II. In Germany, a "stylized" circled cross was adopted by a prohibited political party, leading to a ban of the symbol if used within a context of promoting racism. Although there were doubts on the constitutionality of the ban, it was upheld in a decision of the supreme court. In Italy, there is a similar ban based on Legge Mancino, although there are some examples of the use of the circled cross as a Roman Catholic symbol in Northern Italy.
There is no formal code point in Unicode for this symbol, though other symbols representing the sun are included. Symbols designed for other purposes, such as, and, may be considered as alternatives.
