The Triquetra

The triquetra is a symbol formed by three interlocking arcs, creating a three-cornered knot that has neither beginning nor end. In modern witchcraft and Pagan practice, it is most strongly associated with the Triple Goddess and with the power of three that runs throughout Western magickal thought. Its clean geometry and unbroken line make it equally suited to protective talismans, altar decorations, and dedication jewelry.

The symbol’s visual logic is its completeness: three equal parts, woven together, unable to be separated without dissolving the whole. This quality makes it a natural symbol for any threefold teaching, whether that is the Triple Goddess, the three realms of Celtic cosmology (land, sea, and sky), the three phases of the moon, or the three dimensions of time.

History and origins

The triquetra appears in Celtic-influenced manuscript art, most famously in the Book of Kells, an illuminated gospel book created by Irish monks around 800 CE. It appears there as decorative knotwork rather than a religious symbol in itself. Similar forms appear on Norse runestones and in Germanic metalwork of the early medieval period.

What the symbol meant to pre-Christian peoples of northern and western Europe is not documented in any surviving written source. Scholars can describe where the symbol was used but cannot state with confidence what it signified. Claims of ancient goddess worship tied specifically to the triquetra are part of later interpretive tradition rather than documented history.

The triple-knot gained new meaning in nineteenth and twentieth-century occult and Pagan revival movements. When Wicca and modern Paganism developed in the mid-twentieth century, the triquetra became closely associated with the Triple Goddess theology that Dion Fortune, Robert Graves, and Gerald Gardner each contributed to articulating. The symbol gained wider public recognition through its use on the television series Charmed (1998 to 2006), after which it entered widespread popular use as a witchcraft emblem.

In practice

Practitioners use the triquetra as a focal point for intentions connected to the number three: beginning-middle-end cycles, the waxing-full-waning moon, and all workings that move through phases rather than landing at a single fixed outcome. It is well suited to ritual objects marking a commitment to a goddess who has three faces.

To dedicate an object with the triquetra, you might trace the symbol three times on the object while naming each aspect of the triple quality you are invoking. For Triple Goddess work, name Maiden, Mother, and Crone in turn, breathing a quality of each into the object with each tracing. Finish by placing both palms over the symbol and stating your intention clearly.

The triquetra also serves as a protective symbol drawn on doorframes, notebooks, or skin, where its unbroken line signifies continuous protection and the interlocking structure signifies resilience.

Symbolism

The three arcs of the triquetra form three vesica piscis shapes where they intersect at the center, a form that in sacred geometry represents the space between worlds or the meeting point of two realms. Many practitioners see this central triangular space as the point of power within the symbol, the place where the three become one.

The absence of corners and the continuous looping line connect the triquetra to concepts of infinity, cyclical time, and the eternal nature of the divine feminine. It sits comfortably alongside other knot-based protective symbols in the broader Western tradition, where the idea that a tied or woven line confounds harmful forces is very old indeed.

In myth and popular culture

The triquetra’s most documented historical appearance is in the Book of Kells, completed around 800 CE at an Irish or Scottish monastery. There it appears as a decorative motif within the Gospel text, woven into carpet pages and initial letters alongside other knotwork patterns. Its use there reflects the broader insular art tradition of interlace rather than any specific theological program, though the symbol’s resonance with the Christian Trinity became an association that Christian artists later cultivated deliberately.

In Norse contexts, a three-cornered knot related to the triquetra appears on the Gotland picture stones and in other Viking Age artifacts, though its meaning to the people who carved it is not documented in written sources. Modern Heathen and Norse Pagan practitioners have adopted it alongside the Valknut and other traditional symbols.

The triquetra received its widest popular exposure through the television series Charmed, which aired from 1998 to 2006. The show used a triquetra as the symbol of the three Halliwell sisters and their collective power, placing it prominently on the Book of Shadows that served as the central prop. This use directly reflected and amplified the symbol’s Wiccan associations, introducing it to millions of viewers unfamiliar with Pagan practice, and the Charmed version of the symbol became a widely recognized shorthand for witchcraft in popular culture.

Myths and facts

Several misunderstandings about the triquetra circulate, particularly following its popularization through media.

• Many people assume the triquetra is an exclusively Celtic symbol with a specific pre-Christian meaning. It appears in Celtic-influenced art, but its original significance to pre-Christian peoples is not documented; claims of ancient goddess worship specifically attached to it are later interpretive additions.
• The triquetra is sometimes presented as a specifically Wiccan symbol invented in the twentieth century. It predates modern Wicca by well over a thousand years and was used in Christian as well as Pagan contexts before its adoption by modern practitioners.
• A common belief holds that the triquetra and the triskelion are the same symbol or interchangeable. They are distinct: the triquetra is formed by interlocked lobes or arcs, while the triskelion uses three rotating spirals or legs extending from a center point.
• Some practitioners assume that the central triangular space in the triquetra has a universally agreed symbolic meaning. Practitioners assign various meanings to it, but no single interpretation is canonical; the significance is developed personally or within specific traditions.
