Spiral: Prehistoric Symbol, Nature, Mathematics and Spiritual Readings
The spiral is a curve that coils around a centre: Newgrange, Malta, the Māori fern frond, galaxies, shells. Nature and mathematics (the golden spiral, the nautilus) and the symbolism of the cycle.
Key points
| Definition | A curve that winds around a point while moving away from or toward it |
|---|---|
| Earliest traces | Neolithic carvings (Newgrange, Malta) |
| Archimedean spiral | The gaps between the turns are constant |
| Logarithmic spiral | Grows in proportion; Bernoulli called it the “marvellous spiral” |
| In nature | Galaxies, hurricanes, shells, ferns, sunflowers |
| Symbol | Cycle, growth, evolution, return to the centre |
| Common misconception | The nautilus does not follow the golden spiral exactly |
What is a spiral?
A spiral is a curve that turns around a central point while moving away from it (or toward it). It differs from the circle, which returns upon itself: the spiral advances as it turns. It suggests both movement and the memory of passage.
Several types are distinguished. The Archimedean spiral keeps regular gaps between its turns, like a hose wound on a reel. The logarithmic spiral widens in proportion: each turn is larger than the last by the same factor, which gives it the look of a seashell. The golden spiral is a special case, linked to the golden ratio.
The first spirals: the Neolithic
Spirals are among the very first motifs carved by humans. At Newgrange, in Ireland, a passage tomb dating from the late 4th millennium BC (around 3200 BC), the entrance stone bears spirals; the Neolithic temples of Malta also contain them. They appear across Europe, Asia, the Americas and Oceania.
Their exact meaning is unknown. Hypotheses range from representations of the sun or water to depictions of the path of the dead. Caution is needed: we interpret them with today's eyes.
In nature
| Phenomenon | Spiral |
|---|---|
| Spiral galaxies (including the Milky Way) | Spiral arms; the Milky Way is a barred spiral |
| Hurricanes and cyclones | Rotation with spiralling cloud bands |
| Shells (snail, nautilus) | Regular growth that traces a logarithmic spiral |
| Ferns | Young coiled fronds |
| Sunflower, pine cone | Spiral arrangements whose counts often follow terms of the Fibonacci sequence |
These spirals are physical or biological responses: rotation, growth or the efficient use of space. They are not all identical.
The golden spiral and the nautilus: a common misconception
It is often said that the nautilus follows “the golden spiral”. Published measurements show that its shell is indeed a logarithmic spiral, but that its growth rate is not that of the golden spiral. Many illustrations that superimpose the two are adjusted by eye.
The mathematician Jacques Bernoulli (1654–1705) was fascinated by the logarithmic spiral, which he called spira mirabilis. He is said to have asked for one to be carved on his tombstone, with the Latin motto Eadem mutata resurgo (“I rise again, changed, the same”); the story goes that the stonemason carved an Archimedean spiral instead. The anecdote is famous, and somewhat embellished.
In cultures
- Māori koru: the unfurling fern frond is a central motif of Māori culture, a symbol of new life, growth and peace. It is often worn, but it is a motif of a living culture; learn about its meaning.
- India: the coiled serpent of kundalini is an image from yogic tradition; accounts describe a serpent coiled several times at the base of the spine.
- Celtic Europe: spirals decorate objects from the Iron Age; their exact meaning is lost.
- Contemporary art: the spiral is a motif used by many artists, from Van Gogh (the sky of The Starry Night) to Robert Smithson (Spiral Jetty, 1970).
As with the other symbols in this dictionary, avoid claiming that an entire culture had a single meaning for the spiral.
Current symbolic readings
The spiral suggests progress that returns to what it has already covered, but further on: we revisit the same themes at another level. Depending on the reading, it represents time, evolution, the path toward the centre or away from it, grief that moves forward by returning, or creativity.
It can also be a warning: the “negative spiral” is the image of a thought that loops and worsens. If you feel you cannot get out of it, speak to a health professional.
Using it today
As a pendant, a ring or a tattoo, the spiral is a discreet motif. You can also trace it as an exercise in calm: slowly draw a spiral inward, following your breathing, then return outward.

Frequently asked questions
What does the spiral symbolise?
Movement, growth and the return to the centre. Meanings vary across cultures.
Is the spiral always the golden spiral?
No. The golden spiral is just one particular logarithmic spiral. The nautilus does not follow its rhythm exactly.
What does the Newgrange spiral mean?
We do not know. Specialists propose several hypotheses, but none is proven.
What is the Māori koru?
The motif of an unfurling fern frond, a symbol of new life in Māori culture.
Can one wear a spiral without understanding it?
Yes, it is a universal motif. For a specific cultural symbol such as the koru, learn about its meaning.
