An ancient ornamental and sacred symbol of the peoples of central and northern Europe. Given the neutrality of symbols as such, it is worth noting that the modern scope is significantly different from the original.In the Bronze Age, the triquetra was one of the symbols of the movement of the Sun, personifying the main positions of the luminary (respectively, at sunrise, at the zenith and at sunset). There have been suggestions about the connection of the symbol with the lunar phases and the renewal of life. The sign was very common among the northern peoples of Europe - the Celts, Frisians, Scandinavians. In particular, the sign is present on Celtic crosses, where it is believed to symbolize the triad and is a symbol of the sea god Manannan. In Scandinavian and Teutonic symbolism, the sign is associated with Thor.
