A “Form-Fitting” Knidos Labyrinth

Sometimes you will get a diamond-shaped, empty element in the middle part of a Knidos labyrinth which is formed normally by a cross. This happens when all the paths have the same width and the walls are aligned to them. This form arises because the four turning points form a square.
A shift of the rhomb may also result if one brings into line the entrance axis (of the path into the labyrinth) and the entry axis into the center of the labyrinth with the main axis of the labyrinth figure. In the “twisted labyrinth” I have demonstrated this already once (see related posts below).

If one wants to give a certain shape to this “empty form”, one can play with the position of the turning points. I have done this to get the “form-fitting” labyrinth. All elements are arcs, however, the four turning points do not lie any more in a square.

The suggestion for this labyrinth dates to the logo sketched by the Swiss artist Agnes Barmettler with the woman in the labyrinth for the public women’s places.

Such a labyrinth can be drawn nicely, but is hard to build, above all as a big labyrinth. Hence, I have tried to develop the shape for this labyrinth with geometrical elements only. Some imagination is asked of course. Anyway, the “empty space” offers creative leeway.

The following layout drawing for a sort of prototype shows the geometrical qualities in detail.

Who looks accurately and compares to the original Knidos labyrinth, recognises that one segment less arises. The turning point below on the right is laid in the lengthening of the line from the midpoint of the center and the upper right turning point. The usually narrow “cake piece” is thereby lost in this area.

The drawing

Who would like to build such a labyrinth, is invited warmly to it. The drawing contains all that is neccessary. Indeed, one can also use other parametres, because the labyrinth is scaleable. The underlying values are based on the dimension between axes of 1 m. This means that all details changes proportionally (are reduced or extended). If one wants, e.g., a half as big labyrinth, one multiplies all measures by 0.5. One can even proceed in such a way with “crooked” numbers to get the desired result.

The Two Seed Patterns of the Labyrinth

After you have seen several times the different seed patterns in the labyrinth, now a common consideration should follow: There is the seed pattern for the walls (limiting lines) and the seed pattern for the path, the so-called Ariadne’s thread.

While I tried to build a geometrically exact labyrinth from the different patterns, it has struck me that both seed patterns are not so different at all. And thus I would like to show both together.

Here first the square which four sides are divided into eight constant parts. In a drawing one can take squared paper and make every side 4 cm long. In  reality this would be four metres and the drawing would be on a scale of 1:100.

The scaled square

The mark and name of the different points already states something about the later use within the construction. “A” is the starting point; “Z” the goal or the centre, at the same time, however, also a centre of different arcs. Hence, marked with a bigger symbol of a circle. As well as the four corner points M1 to M4, also centres of arcs. And at same time delimiters for the walls.
The path axes (Ariadne’s thread) are marked with a small cross and are numbered from 1 to 7. In between are the walls which are marked with small circles.

However, the lines must not be angular, they can also be rounded and then the pattern looks like above.

If both patterns are shown together, one recognises the relationship and resemblance between them. And also that the centres of the different arcs are same. No surprise, because the lines are parallel and the red thread is, finally, the middle between the black boundary lines, so to speak the path axis.

Afterwards I would like to point out which arcs are constructed from a total of five centres. There are quarter circles and semicircles which run in each case in different sectors. The order is as you like, since basically it makes no difference which curve is drawn or constructed first. This arises by itself, if one applies the principle for the drawing of a labyrinth properly. As it was described in the older posts on this blog.

If you would like to build such a labyrinth, you will find all specifications and all radii in this design drawing on a scale of 1:100. It is a sort of prototype for a dimension between axes of  1 m and scalable.

The 3-Circuit Classical Labyrinth

The labyrinth in its simplest form is one with 3 circuits. For some people it is not a “real” labyrinth because the path is leading directly into the centre without being closer and then farther away from it.
As there is no universally valid definition for the labyrinth, we may nevertheless consider this labyrinth as a real one.

How do we get one?

The basic pattern to make a 7-circuit classical labyrinth is known, in the meantime, probably by all readers of this blog. (If not, please take a look here.)

No 3-circuit historical labyrinths are known, it is made from a reduction of the basic pattern. If one omits the four angles, only the cross and the four dots are remaining.

This reminds a little: Dot, dot, comma, dash – smiley face in a flash :-). However, it is really so simple to make a labyrinth, and this is why it is a child’s play to draw one this way.

However, there are still other methods to draw the labyrinth: In two lines, from one end of the line to the other end. Try to draw it on a sheet of paper. So often that you can do it by heart.
Tip for right hander: Begin at the left end. Left-handed persons are beginning at the right end. The lines may become crooked.

An other variation would be to begin in the central intersection point and to draw to all four directions. This has practical meaning if one would build a labyrinth with different material for example.
With four lines

With four lines

The most elegant method is to draw the labyrinth in one line. Therefore we take the path, the famous thread of Ariadne. We can begin on the inside or from the outside.

Who realises this by heart, maybe even for the 7-circuit labyrinth, may be called labyrinth expert.

The Lines in a Labyrinth

There are many possibilities to design a labyrinth .

Some of it were already introduced here. Still more are following. In addition it is however good to look more exactly to the lines  of a classical labyrinth.

The Knidos labyrinth in 2 colours

The Knidos labyrinth in 2 colours

In this two-coloured drawing one can see very good that the labyrinth consists of 2 crossing lines. The one (here green here) line leads from the upper, left turning point to the lower right turning point. The other (here brown) line leads from the lower, left turning point to the upper, right turning point.

We look at the border lines of a classical labyrinth with large centre and 7 circuits. The path (Ariadne’s Thread) runs between the lines.

The Knidos labyrinth in 4 colours

The Knidos labyrinth in 4 colours

In this four-coloured drawing the lines begin/end in each case in the centre and end/begin at the 4 turning points.

It is more difficult to draw a labyrinth according to these specifications; the well-known basic pattern is much simpler. But it is more practical, if I want to place a labyrinth from ropes e.g.. How to do that exactly, we will see in a later post.

Ariadne's Thread

Ariadne's Thread

Here we have only one line before us. That is the way, or also the so-called thread of Ariadne  or the proverbial red thread. It is a uninterrupted line, which is not crossing anywhere and which leads on a devoured, but direct way from one end (at the beginning) to the other end (in the centre); and vice versa.

It is worth to remember the layout of this line to incorporate the labyrinth. The practical application is to step a labyrinth into the snow or to mow one into a meadow. Because then I build the path and not the delimitation.
