Triquetra

Triquetra (Template:Pron-en) is a word derived from the Latin tri- ("three") and quetrus ("cornered"). Its original meaning was simply "triangle" and it has been used to refer to various three-cornered shapes. Nowadays, it has come to refer exclusively to a certain more complicated shape formed of three vesicae piscis, sometimes with an added circle in or around it. This has been used as a religious symbol of things and persons that are threefold.

Ancient usage

Germanic paganism

The triquetra has been found on runestones in Northern Europe and on early Germanic coins. It presumably had pagan religious meaning and it bears a resemblance to the Valknut, a symbol associated with Odin.

Celtic art

The triquetra is often found in Insular art, most notably metal work and in illuminated manuscripts like the Book of Kells. It is also found in similar artwork on Celtic crosses and slabs from the early Christian period. The fact that the triquetra rarely stood alone in medieval Celtic art has cast reasonable doubt on its use as a primary symbol of belief. In manuscripts it was used primarily as a space filler or ornament in much more complex compositions, and in knotwork panels it is a design motif integrated with other design elements. Celtic art lives on as both a living folk art tradition and through several revivals. This widely recognized knot has been used as a singular symbol for the past two centuries by Celtic Christians, Pagans and agnostics as a sign of special things and persons that are threefold.^[1]

Christian use

The symbol was later used by Christians as a symbol of the Trinity (Father, Son and Holy Spirit). This appropriation was particularly easy because the triquetra conveniently incorporated three shapes that could be interpreted as Christian Ιχθυς symbols.

A very common representation of the symbol is with a circle that goes through the three interconnected loops of the Triquetra. The circle emphasizes the unity of the whole combination of the three elements.

Modern use

Neopaganism

Modern Pagans use the triquetra to symbolize a variety of concepts and mythological figures.

Germanic Neopagan groups who use the triquetra to symbolize their faith generally believe it is originally of Norse and Germanic origins. Due to its presence in insular Celtic art, Celtic Reconstructionist Pagans use the triquetra either to represent one of the various triplicities in their cosmology and theology (such as the tripartite division of the world into the realms of Land, Sea and Sky),^[2] or as a symbol of one of the specific triple Goddesses, for example, The Morrígan.

The symbol is also sometimes used by Wiccans and some New Agers to symbolize either the Wiccan triple goddess, the interconnected parts of our existence (Mind, Body, and Soul), or many other concepts that seem to fit into this idea of a unity.

Popular culture

The triquetra is often used artistically as a design element when Celtic knotwork is used. Many who identify as Modern Celts may use the symbol to display an identification with Celtic culture, whether they live in the Celtic Nations or the diaspora.
In recent years, the symbol has become well-known due to its use on the cover of the "Book of Shadows" used by the three sisters on the American TV show Charmed. It represents the three sister witches working together as one.
