A Roman soldier stationed in Britain around 200 CE carved a symbol into a stone wall near Hadrian’s Wall. It was a simple four-pointed loop, continuous, no beginning and no end. Seventeen centuries later, a witch in New England scratches a similar shape into a candle with a pin before lighting it. The Celtic knot and the witches knot are both unbroken loops drawn for protection, but they belong to different worlds: one is a decorative art form rooted in early medieval Christian manuscript illumination, the other is a working magical sigil used in folk witchcraft and modern pagan practice. The difference is not just visual. It is a difference of purpose, origin, and how the symbol behaves in the hand.
The Celtic knot (or triquetra, quaternary knot, endless knot) is a geometric design of interwoven strands with no visible start or end, found in Insular art from the 7th century onward. The witches knot (also called the witches’ foot or devil’s foot) is a four-pointed, looped sigil drawn in a single continuous line, used in folk magic for protection, binding, and warding. One is carved in stone and illuminated in vellum. The other is scratched in wax, drawn in ash, or traced in the air.
Where Do Celtic Knots Come From?
The earliest surviving Celtic knots appear in the Book of Durrow (c. 650–700 CE) and the Lindisfarne Gospels (c. 700 CE). These manuscripts were produced in Irish and Northumbrian monasteries, where scribes adapted motifs from earlier pagan metalwork and Roman decorative traditions into a new Christian visual language. The knots were not originally called “Celtic.” That label came much later, during the Celtic Revival of the 19th century, when antiquarians like Sir William Betham and artists like George Bain popularized the term.
The knots served a theological purpose. The unbroken line represented eternity, the infinite nature of God, or the interwoven unity of the Trinity. The triquetra, a three-pointed knot, was used explicitly as a Trinity symbol. The quaternary knot, with four loops, could represent the four Gospels or the four elements. But these meanings were never fixed. A knot in the Book of Kells (c. 800 CE) might frame a sacred text without any doctrinal commentary attached. The symbol was the ornament, and the ornament was the prayer.
By the 10th century, Celtic knotwork had spread beyond manuscripts into stone crosses, metalwork, and jewelry. The Muiredach Cross at Monasterboice (c. 900 CE) is covered in interlace patterns that echo the manuscript tradition. The knots were carved by craftsmen who understood geometry, not magic. They were not talismans. They were decoration in service of faith.
Where Does the Witches Knot Come From?
The witches knot has a different genealogy. It appears in European grimoires and folk magic records from the 16th century onward, though its roots are older. The symbol is a variant of the hexafoil or Solomon’s knot, a six-pointed loop found in Roman mosaics and medieval church floors. But the witches knot specifically has four loops, not six, and it is drawn in a single unbroken line.
The earliest clear reference to a witches knot in magical practice comes from the Key of Solomon, a grimoire compiled in the 14th or 15th century but widely circulated in the 16th and 17th centuries. In that text, the knot appears as a protective sigil to be drawn on the threshold of a room or on a tool used in ritual. The name “witches knot” is later. It appears in 19th-century folklore collections, where it was associated with the idea that witches could draw a knot in the air to bind someone’s power or to create a protective circle.
In folk practice, the knot was drawn on the floor in chalk or ash, on a candle with a pin, or on the skin with a finger. It was not a decorative motif. It was a working tool. A witch might draw the knot on the door of a stable to keep livestock safe, or on a piece of paper to be burned for protection. The knot was a lock. It held something in or kept something out.
What Do the Symbols Actually Look Like?
The visual difference is straightforward once you know what to look for.
A Celtic knot is an interlace pattern. Multiple strands weave over and under each other in a repeating loop. The triquetra has three arcs that meet at a central triangle. The quaternary knot has four loops arranged around a central square or diamond. The strands are thick, often decorated with ribbon-like bands, and the design is symmetrical. The knot is meant to be seen, admired, and contemplated.
A witches knot is a single continuous line that loops back on itself four times, forming a shape that resembles a four-leaf clover or a stylized foot. The line never crosses itself in the same way a Celtic knot does. Instead, it curves inward and outward, creating four distinct lobes. The witches knot is often drawn small, quickly, and without ornament. It is meant to be used, not displayed.
One is a painting. The other is a signature.
How Are They Used in Practice?
That history explains why the two symbols behave differently in the hand. A Celtic knot is carved or drawn with care, meant to last. A witches knot is drawn with intention, meant to work.
In modern pagan practice, the witches knot is used for protection, binding, and warding. A common method: draw the knot on a candle with a pin or a piece of charcoal, focusing on the intention. Light the candle and let it burn down. The knot is activated by the act of drawing it, and the fire releases the intention. Another method: draw the knot on a piece of paper, fold it, and carry it in a pouch or place it under a threshold. The knot is a seal. It keeps the boundary intact.
The Celtic knot, by contrast, is rarely used as a working magical tool. It appears on altars, in jewelry, and in ritual spaces as a symbol of eternity, continuity, or the interconnectedness of all things. A practitioner might wear a triquetra pendant to remind themselves of the threefold nature of existence. But they would not scratch a triquetra into a candle for a spell. The knot is not a sigil. It is a symbol.
That distinction matters. A sigil is a symbol charged with a specific intention. A symbol is a sign that carries a general meaning. The witches knot is a sigil. The Celtic knot is a symbol. One is a tool. The other is a reminder.
What Do People Get Wrong?
The most common misconception is that the two knots are interchangeable. They are not. A Celtic knot drawn in a magical context is not a witches knot, and a witches knot carved in stone is not a Celtic knot. They come from different traditions, serve different purposes, and carry different meanings.
Another misconception: that Celtic knots were originally pagan symbols co-opted by Christianity. This is not supported by the evidence. The earliest Celtic knots appear in Christian manuscripts, not in pre-Christian artifacts. The Book of Durrow and the Lindisfarne Gospels are monastic works. The knots were invented in a Christian context, not borrowed from a pagan one. The idea that they are “ancient Celtic” symbols is a 19th-century Romantic invention.
A third misconception: that the witches knot is a satanic symbol. It is not. The name “devil’s foot” comes from 19th-century folklore, where it was said that the devil left a four-toed footprint. But the symbol itself has no connection to Satanism. It is a protective sigil used in folk magic, not a mark of worship.
FAQ
Can you use a Celtic knot in witchcraft? Yes, but it functions as a symbol of eternity or interconnectedness, not as a working sigil. It is appropriate for altars, jewelry, or ritual spaces where its meaning supports the intention.
Is the witches knot the same as a pentagram? No. The pentagram is a five-pointed star. The witches knot has four loops. They are different symbols with different histories and uses.
Do Celtic knots have magical meanings? Not in their original context. They were decorative and theological. Modern practitioners may assign magical meanings, but those are contemporary interpretations, not historical facts.
How do you draw a witches knot correctly? Start at the top, draw a loop to the right, curve down to the bottom, loop to the left, curve up to the top, and close the line. The key is a single unbroken stroke. Practice on paper before using it in ritual.
The Celtic knot and the witches knot are both loops without ends. But one was drawn by a monk in a scriptorium, and the other was scratched by a witch in a candle. They belong to different worlds, and they ask different things of the hand that draws them. If you are looking for a symbol to wear, choose the Celtic knot. If you are looking for a symbol to work, choose the witches knot. The difference is not in the line. It is in what you do with it.
