A visitor to Newgrange in County Meath stands before the entrance stone. The limestone is carved with a triple spiral, three arcs that coil from a shared center and spin outward. Forty miles away in Dublin, a page of the Book of Kells shows a three-cornered knot of interlaced ribbons, looped into a triangle with no beginning and no end. Both are called Celtic. Both hold three. A casual eye reads them as interchangeable. A closer one sees that the spiral and the knot answered different questions.
The triskele (also triskelion) is a motif of three curved branches or spirals radiating from a single point. The trinity knot (triquetra) is a continuous interlace of three arcs forming a triangular knot. One opens outward; the other closes in on itself.
What the Spiral and the Knot Actually Mean
We define them by form and function.
The triskele consists of three linked spirals (or three bent legs, in the Greek triskelion) that move in the same rotational direction. In the Neolithic examples at Newgrange (circa 3200 BCE), the spirals are incised into stone with no clear evidence of symbolic intent — the builders left no text. By the time the Celts encountered the motif, it had been reused for over two millennia. Early Irish Christian scribes later adapted the triskelion into manuscript decoration, but its pre-Christian meaning is inferred: motion, cycle, the threefold division of the world (land, sea, sky) or time (past, present, future).
The trinity knot, or triquetra, is a woven triangle formed by three overlapping arcs. Its earliest appearances in Celtic contexts are in illuminated gospels such as the Book of Kells (circa 800 CE) and on high crosses like the Cross of Muiredach (tenth century). The word triquetra is Latin for “three-cornered.” Christian scribes used it to represent the Trinity — Father, Son, Holy Spirit, without breaking the iconoclastic ban on depicting God. The knot has no visible start or stop, which suited a doctrine of a God without beginning or end.
Practitioners today often use both symbols, but they carry different weight in ritual. The triskele suggests movement, action, the turning of the year. The trinity knot suggests binding, unity, a closed circuit of protection.
Where They Came From: Dates, Objects, and People
The oldest surviving triskele in Ireland is on the entrance stone of Newgrange, a passage tomb that predates the Celtic arrival on the island by roughly two thousand years. Archaeologists call the carvings “megalithic art” and have found similar three-spiral motifs at Loughcrew and Knowth. No one knows what the builders called them. The term triskele comes from the Greek triskeles (“three legs”) and appears first in classical descriptions of the Sicilian triskelion, a symbol of the island’s triangular shape. The Celtic version is a later borrowing.
The trinity knot appears in the Book of Kells around 800 CE. The scribe(s) of the book, likely monks on the island of Iona, used interlace patterns derived from earlier Germanic and Mediterranean models. The triquetra is one of many knot forms, the four-cornered tetraskelion and the complex zoomorphic interlaces also appear. By the twelfth century, the trinity knot was a standard motif on Irish high crosses and in metalwork such as the Ardagh Chalice (eighth century). It had no independent existence in pre-Christian Celtic art. That matters because modern pagans sometimes claim it as an ancient goddess symbol. The evidence does not support that.
A human consequence: for an eighth-century Irish monk copying the Book of Kells, the triquetra was not a goddess. It was a theological shorthand. For a modern neopagan, it can be both, but knowing the difference between origin and appropriation is part of informed practice.
How the Symbols Work in Practice
We use the triskele when we want to mark a beginning. Its three arms read as a verb: rotate, progress, change. In modern Druidry, the triskele often represents the three realms (land, sea, sky) or the three cycles of life (birth, death, rebirth). Some practitioners spin a triskele pendant or draw it in the air to open a ritual space. Because the spiral is open at the end, it suggests continuity, the path does not close.
We use the trinity knot when we want to bind something. Its three loops interlock without ends, making it a natural emblem for vows, marriages, or pacts. In folk magic, a triquetra drawn on a threshold or carved into a door frame is said to prevent malevolent spirits from crossing because they cannot find the opening. The knot works like a labyrinth: it confuses. That functional difference, motion versus containment, is what seperates the two symbols in actual use.
If you wear a triskele, you signal movement through cycles. If you wear a triquetra, you signal unity and protection. Neither is wrong. They are different tools.
Triskele and Triquetra Compared: What the Form Reveals
The closest adjacent symbol to the triskele is the swastika, another rotational motif found across Neolithic Europe. The closest to the trinity knot is the four-ring Celtic knot, which shares the interlace structure but adds a fourth loop.
Both symbols are triple, but triple for different reasons. The triskele’s three is quantitative: three parts that together form a whole in motion. The triquetra’s three is qualitative: three aspects of a single unity. The triskele implies change; the triquetra implies permanence. That is why medieval Christians adopted the knot and not the spiral: a God who is three-in-one cannot be shown as three separate moving parts without suggesting polytheism.
Sources disagree on whether the triskele had a specific religious meaning for the Celts. No written record from the Iron Age survives. The claim that it represents the triple goddess (maiden, mother, crone) is a twentieth-century invention, popularized by Robert Graves in The White Goddess (1948). We can state that as history without dismissing its value for modern practitioners.
Common Misconceptions
The triskele and trinity knot are the same symbol. They are not. The triskele has three separate spirals or branches. The triquetra has three continuous arcs that interlace. The difference is structural: open versus closed.
The trinity knot is a pre-Christian Celtic symbol. It appears in Christian manuscripts and metalwork. The argument that it was “borrowed” from pagan traditions has no archaeological or textual support. It may ultimately derive from interlace patterns that predate Christianity, but the specific three-looped knot is a Christian development.
The triskele is uniquely Irish. It appears in Mycenaean Greece (on a vase from the fourteenth century BCE), in Sicily (as the triskelion), and in East Asian art. The Irish stone version is the oldest surviving example in northern Europe, but not the only one.
Both symbols are interchangeable in rituals. Some practitioners use them that way, but they were designed for different functions. The triskele turns; the triquetra holds. Swapping them without understanding the distinction muddles the intention.
FAQ
Is the triskele the same as the triquetra?
No. The triskele has three separate spirals or legs; the triquetra is a continuous three-loop knot. The terms are not interchangeable.
Which symbol is older?
The triskele. The Newgrange carvings date to approximately 3200 BCE. The triquetra appears no earlier than the eighth century CE in Celtic contexts.
Can I use both in my practice?
Yes. Many practitioners do. Use the triskele for cycles and movement; use the triquetra for protection, binding, or union.
Do these symbols belong to closed traditions?
No. Both appear in multiple cultures and time periods. The triskele in particular is not limited to Celtic reconstructionist practice. The triquetra, while Christian in its early Celtic context, has been adapted widely. No one group owns them.
Toward Deeper Knowledge
The triskele and the trinity knot are two ways of saying “three is sacred.” One opens a path; the other closes a circle. For a fuller treatment of how triple motifs appear across European talismanic traditions, see our guide to talismans and amulets. The glossary entry for triquetra covers its manuscript history in more detail. And if you are working with Celtic protective symbols, the Brigid’s cross ritual shows how another triple symbol, the sunwheel, was Christianized without losing its older geometry. Each knot and spiral has its own grammar. Learn to read it, and the symbol speaks.
