Question for the: Topic Challenge #1 – Famous Designers

I remember as a kid my favourite book in the whole house wasn't a book of fairy tales or colourful illustrations. It was The complete works of M.C. Escher. I could stare at his works for hours on end. Trying to wrap my head around how those little people could go up and down the stairs forever.

But what intrigued me even more were his Tessellation pieces, where he would divide a plane into interlocking figures, such as here:

enter image description here

Later, in his Metamorphosis pieces, he would take this a step further and morph one tesselation into another, like so:


Nowadays, it's pretty trivial to get a computer to calculate an optimal tesselation, but Escher didn't have any of that. And the metamorphosis works add a whole new level of complexity even a computer would find hard to do. So my question is quite simply: How did Escher make his art? If I wanted to do something similar today, how would I go about it?

    As you can read in my answer, you made my day with this question. :o) – Rafael Apr 28 '17 at 23:46

    Black magic. Actually, he was a good guy -- probably white magic ✨ – plainclothes Apr 29 '17 at 1:53
  • When I google your question the first result is a site dedicated to tessellation: tessellations.org. There are quite a few methods which Escher could have used. And some words about him too. – Wolff May 5 '17 at 16:09

With a pattern.

In this case a 3 axis grid (triangular). enter image description here

Once you know what to draw on each piece, you need to repeat this. You can have and use sub-patterns or smaller ones to be more exact.enter image description here

These patterns are pretty easy to draw, and they are used for example in architecture in different cultures. We are used more to a square pattern, but this triangular pattern can produce hexagonal and rhomboidal patterns as well.

enter image description here

And you can play with it to start building ripples, but still, you repeat the internal objects on this now deformed patterns.enter image description here

Look how many patterns you have with this triangular grid.enter image description here

Grab a paper and a ruler, draw some pages and find some more patterns!

This is a typical example of introductory classes at the University. We called it "Little Squares 101" Or "Sticks and Balls II" (That was the second course) and yes, we drew this by hand.

You can also see these patterns in 3D often used in Architecture.


Regarding the comment:

I really see no difficulty to draw this lizard by hand. Look at the second image, it clearly marks the middle of the triangle and where the legs should intersect them. I would probably have a reference drawing but draw those by hand. Especially if the next lizard will turn into a duck... Metamorphosis...

Additionally, comparing two lizards they are not exactly the same.enter image description here

When you are using a pattern, you let the pattern guide you.


Edited some years later. Let us explore how Escher used these grids to develop part of his work.

Here is a screen capture of the website: https://mcescher.com/gallery/symmetry/

where you can see how he used a two-axis grid rotated 45° next to a work using a three-axis grid. The grid even shows in pencil.

enter image description here

The grid is only a starting point. You have some other resources like mirroring, rotating, and scaling. But art is about taking the resources you have as a guideline, not as a limitation.

Here the "deformation" of the grid is extreme, the grid itself has its own new shape:

Remember that you can create subpatterns (smaller ones) or superpatterns (bigger ones)

  • Hey @Rafael, thanks! Good answer! Although I'm also interested in the mechanical part. Did he actually draw each of the creatures by hand, or did he use some kind of stencil? – PieBie Apr 29 '17 at 22:25
  • I have no idea. Some of his work is woodcarving, lithography, drawings. I really see no difficulty to draw this lizard by hand. Look at the second image, it clearly marks the middle of the triangle and where the legs should intersect them. I would probably have a reference drawing but draw those by hand. Especially if the next lizard will turn into a duck... Metamorphosis... – Rafael Apr 30 '17 at 1:36

Actually this lizard is created on the basis of a hexagon, not a triangle! Here is the hexagon:

enter image description here

Here is a movie how to deform the hexagon to get the lizards:
https://youtu.be/T6L6bE_bTMo?t=10

You might be tempted to think a triangle would suffice to make lizards because we may divide a hexagon into six triangles. How do we know a triangle would not suffice? Because then each triangle has to have a different pattern painted on it and we need six such triangles. Let's check for example the triangle made with vertexes where all three lizards heads meet:

enter image description here

Of course, we can tessellate this triangle (or any triangle cut out from original drawing) but it will not produce lizards. The poor beasts made from this triangle would not have limbs on the right side. We need all six triangles to make the Escher's tessellation complete. The hexagon is the smallest geometric figure which makes the lizard tessellation possible with a single pattern.

    What is a hexagon but a field of triangles with a specific configuration. See redblobgames.com/grids/hexagons – joojaa Sep 30 at 13:53
  • This is obviously only true if i dont introduce other rules – joojaa Sep 30 at 14:45
  • I agree but i can construct the same with altered rules that are not tesselation but produce same thing. – joojaa Sep 30 at 15:17
  • I edited my answer because I used the word pattern in the first paragraph, but after reviewing I changed it to the grid. Hexagons are a "subproduct" of putting different triangles together. But the base is a 3 axis grid. And this grid forms triangles as a base. You can have sub-patterns or super-patterns. A hexagon is a super-pattern. – Rafael Sep 30 at 18:27

    @Rafael I am very glad you said you had downvoted. I reedited my answer to make my point clear. In case I was wrong, please show me the triangle with a pattern on it that makes tessellation. – Przemyslaw Remin Sep 30 at 19:45
