The Golden Spiral and Pentagons in Nature

More five sided fun

And more pentagons to mark 5 years of DressCode. This time we are looking at the Golden Spiral, an aesthetic phenomenon that is based on pentagonal mathematics. It's often described as nature and art in perfect harmony. Where the 'golden ratio' and pentagonal shapes are closely linked. It's a model has inspired people for centuries.

Many Artists have woven the Golden Spiral into their work, creating a visual sense of harmony and aesthetic balance that resonates with people Here’s the secret sauce…


Golden spiral pentagons


The golden rule is - when a regular pentagon is inscribed in a circle, the ratio of the circle's diameter to the pentagon's side length is the golden ratio, approximately 1.61803398875.

The Golden Spiral concept can be seen in various natural phenomena, things such as the spiral arrangement of sunflower seeds and even the shape of galaxies.

Pentagons in nature

The pentagon's charm means it doesn’t have to be a perfect geometrical form. Pentagons are found all around us in the natural world. One of the most obvious examples would be any of the numerous five-petaled flowers, things such as the cherry blossom or apple blossom.

These natural wonders demonstrate the harmony and balance found in pentagonal structures, it’s another sign that nature really is amazing, naturally creating and using these shapes.

Religon and pentagons

Pentagons hold spiritual significance for several cultures, often representing harmony, unity and the interconnectedness of things. Not really a surprise given what we know about the Golden Spiral, and the way our brains are hard wired to this aesthetic. The pentagon is associated with the concept of Phi - the golden ratio – mentioned above, also the five elements - earth, air, fire, water, and spirit.

Intricate patterns of pentagons can be found in ancient architecture and religious symbols worldwide, from the mesmerizing Islamic geometric tiles to the mystical pentagonal designs in Celtic art.

Here's 9 of the most famous pieces of art that feature pentagons.


Vitruvian man by Leonardo Da Vinci
  1. Vitruvian Man by Leonardo da Vinci
    I know this is going to appear obvious, but Vitruvian Man always comes front of mind when we think of pentagons. Although the primary focus of this iconic drawing is the representation of 'ideal' human proportions, it contains pentagonal shapes within its geometric construction. The position of the limbs and the navel forms a pentagon within the larger circular shape, Leonardo had a strong interest in the geometric harmony found in the human body.

    Penrose stairs M.C Esher

  2. Penrose Stairs by M.C. Escher.
    We are huge fans of Escher, a master of optical illusions, the Penrose Stairs has another layer of confusion, also being known as 'Ascending and Descending'. Whichever name you use, this image perfectly demonstrates Escher's sublime skill. The artwork features a continuous loop of stairs that seemingly ascend and descend infinitely. Within the design, pentagonal shapes play a role in creating the impossible architectural structure, adding to the mind-bending visual puzzle.

Party on

The party's not over yet! As we conclude this part of the birthday Pentagonal journey, we hope you've been inspired by the magic and wonders of the five-sided shape. Celebrating 5 years of DressCode Shirts with a pentagon theme has allowed us to explore this shape and it's mind bending properties in more depth.

We have been fascinated by the propensity of the pentagonal form in everything from the natural world to mathematics, art, and architecture (more about this in our next blog).

The pentagon is a major part of our visual world, and has been captivating minds for centuries. It’s certainly kept us busy over the past few weeks, and these blogs we hope inspire you, in the same way the number five and five-sided shapes, have inspired us to design this shirt.
