## How to build a Knidos Labyrinth with Ropes

Here you will see another way to build a labyrinth.

The original task was to make  a temporary labyrinth out of ropes in a large room. That seemed to be quite simple, because one knows how a labyrinth looks like, and how to make one from the basic pattern with the square, the four angles and the points in every corner. It should be a classical 7-paths labyrinth with a larger centre. But the question was: How many ropes does one need and where does one begin best?

A rope can easily be moved in curves and switched. Thus finally after longer trying a labyrinth resulted, even if the centre was somewhat small.

After that experience I wanted to know it more exactly and developed a kind of instruction, which shall be presented here.

First I locate some starting points, at which I can orient myself easily and to which I can take reference.

Figure 1

In this example the ways have a width of 50 cm, the centre has a diameter of 2 meters and the entire labyrinth a largest diameter of 9 meters. The points E1 to E4 are the end points of the lines and lie in a square, which can be very simply designed with the diagonal of 2.83 m.

Figure 2

On the basis of the two upper points E1 and E2 I can determine the middle of the centre M through the masses 2.00 m and 1.50 m. This point is temporarily marked, just as the middle of the square. Because from here and around the point M the ropes must be placed.

Figure 3

From the central point I go straight upwards and put then the rope in an even distance of 1 m (= radius 1m) around point M; when I am near E2, I go in a distance of 0.5 m (=Radius 0.5m) around point E2 and put the rope in the even distance of 1 m parallel to the part already lying until point E1. So I have done the red line 8 and 6.

Figure 4

Now the blue line 5 and 7 shall be constructed. I start again in the central square point, goes a piece straight to the right until the points E2 and E4 and turn then to the left and above, by following parallel to and in the distance of 0.5 m the red line 6 already put. At point E1 I circle round this point, then moving between the red line 6 and 8 until point E2. I have put the blue line 5 and 7.

Figure 5

Now it is the turn of the brown line. Again from the central square point I go  first straight until to the points E1 and E3. Then in the distance of 0.5 m parallel to the blue line 5 until the points E2 and E4. The point E4 is circled in a distance of 0.5 m outwards and then I lay the rope parallel to the still lying part of line 4 in the distance of 1 m until point E3. The brown line 2 and 4 is finished.

Figure 6

For completion still the green line is missing. From the central square point I go straight downwards to the points E3 and E4; then I turn to the right in the distance of 0.5 m parallel to the brown line 2 around point E4 and onward until point E3. This point is circled inward in 0.5 m distance and the green line 3 is moved between the existing brown line 2 and 4 up to the point E4. The green line 1 and 3 is done. The labyrinth is finished.

i found a few Labyrinth in the base design of the Gurudwara’s (Sikh worship place) in Nanded, Maharashtra, India. Is it possible to send you the pictures of these Labyrinth?
