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" (a calque of Sonnenkreuz). The symbol means village in Ancient Egyptian (Gardiner symbol O49). The same symbol is in use as a modern astronomical symbol representing the Earth rather than the Sun. In pharmacy, sun cross symbol represents various/miscellaneous drugs. After World War II, variants of the symbol became associated with neo-Nazi and white supremacist movements. 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 (1881) postulated an (unattested) Gothic rune hvel ("wheel") representing the solar deity by the "wheel" symbol of a cross-in-a-circle, reflected by the Gothic letter hwair (𐍈). 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 Sun-Cross or Cross of Wotan", p. 94). 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 (Saint Andrew's 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 (resembling a curved swastika, illustrated below) was popular as a link between Christianity and Germanic paganism in the völkisch German Faith Movement.
