Triquetra

The Triquetra's power as a symbol comes from its structure: one unbroken line that loops into three equal sections without a visible start or end. That continuity is the point — it represents unity within division. In Celtic tradition, the three interlocking arcs stood for the triple nature of existence: land, sea, sky, or the three phases of the moon tied to the triple goddess. Early Christianity adopted the form to represent the Trinity — Father, Son, Holy Spirit — partly because it was already embedded in local visual culture. In Wicca, it maps onto the Maiden, Mother, and Crone aspects of the goddess. The circle sometimes added around it reinforces wholeness and eternity. It's not decorative filler — each tradition that used it meant something specific by the three.

The word Triquetra comes from Latin: tri (three) + quetrus (cornered), meaning 'three-cornered.' The symbol itself predates the name. It appears on Germanic coins from the 1st century BCE and on Norse runestones from the 8th–9th centuries CE, where it was associated with Odin or used as a protective mark. Celtic stonework from Ireland and Scotland carries it extensively, particularly in illuminated manuscripts like the Book of Kells (circa 800 CE), where it fills decorative knotwork panels. Christian missionaries working in Celtic regions absorbed the symbol rather than replacing it, reframing its triple structure as Trinitarian. By the medieval period it was appearing in church carvings across northern Europe. The 19th-century Celtic Revival brought it back into widespread use as a cultural identity marker.

If you want to work with the Triquetra as a focus symbol, start by drawing it freehand — one continuous line, no lifting the pen. It takes a few tries, but the process makes the structure click in a way just looking at it doesn't. Wear it as jewelry if you're drawn to Celtic or Wiccan traditions, but know which meaning you're anchoring it to — triple goddess, Trinity, or the land-sea-sky triad — rather than treating it as generic 'Celtic.' For research, Miranda Green's 'Celtic Symbols' and the Book of Kells facsimile editions are solid starting points. George Bain's 'Celtic Art: The Methods of Construction' breaks down how to draw Celtic knotwork including Triquetra variants.
