Spirals

Spiral design

The spiral, an early symbol for the sun, is the most common ancient symbol found everywhere people have settled or visited. Because ancient people believed the sun died every evening and was reborn in the mornings, spirals decorate ancient tombs, crypts and burial sites to represent this cycle of life, death and rebirth.

You can see growth spirals or whorls occurring in nature. Just look at how how leaves naturally arrange themselves on stems, or the spiral designs on pineapples, artichokes, pine cone, sun flowers and Romanesco broccoli, to name just a few.

Spirals appear virtually everywhere in nature, even in space, just take a look at the Milky Way.

Be sure to check out the Spirangles for more unique, educational fun. Most of the spirangle images are blank shapes so children can practice making their own spirangle patterns.

The spiral, an early symbol for the sun, is the most common ancient symbol found everywhere people have settled or visited. Because ancient people believed the sun died every evening and was reborn in the mornings, spirals decorate ancient tombs, crypts and burial sites to represent this cycle of life, death and rebirth.

Spirals that appear in nature on such things as shells, flower petals, leaves, horns, claws and fingerprints are called whorls.

The spiral has many different forms including:

  1. Archimedean spiral
  2. Cornu spiral
  3. Fermat's spiral
  4. hyperbolic spiral
  5. lituus
  6. logarithmic spiral
  7. spiral of Theodorus

The spiral represented here is the Archimedean spiral.

The Golden Spiral was first noticed by Phythagoras, a Greek mathematician in the 5th century B.C. The Golden Spiral and Fibonacci spiral are very similar.

Artists frequently use spirals in creating works of beauty. The Fibonacci spiral is a logarithmic spiral, also called a growth spiral that often appear in nature.

Golden Spiral or Fibonacci sequences appear in nature such as as how leaves naturally arrange on stems, the spiral designs on pineapples, pine cones, sun flowers as well as in fingerprints, DNA, and the twisting shape of the Milky Way in outer space.

The Fibonacci spiral is created using sequences of Fibonacci-numbers 0 1, 1, 2, 3, 5, 8, 13, 21, and 34.

Good visual instructions for constructing the golden ratio with a compass and straight edge.
