The Wunderkreis and the Baltic Wheel are compound labyrinths which are constructed from curves around different centres. The two lower turning points are proper for the “labyrinthine” circuits, those in the middle for the double spiral.

A Baltic wheel has a bigger, empty center and a short second exit. This is already a double spiral, yet without more twists. Both accesses are normally separated by an own intermediate piece, a sort of shoehorn.

The pattern for the layout is the same one for both labyrinth types. The tool to produce the layout is also the same. The number of the circuits in all can be different, nevertheless.

Here it is only about the method. The geometrically correct construction is another thing again. There are already several posts in this blog about that.

There is no seed pattern like we have it for the well-known classical labyrinth. However, there is a basically very simple method to draw such a labyrinth or to lay it directly with stones or to scratch it in the sand.

A step-by-step instruction should show it. The boundary lines of the labyrinth are drawn, the path runs between the lines.

Step 1

Step 1

Step 1: I draw half a curve upwards, from the left to the right.

Step 2

Step 2

Step 2: I jump a little bit to the left, make a curve downwards to the left, walk round the first curve and land to the right of the preceding curve.
This would already be the center of the Baltic Wheel or the middle of the smallest possible Wunderkreis.

Step 3

Step 3

Step 3: Nevertheless, the double spiral should become bigger. Hence, I jump again a little bit to the left at the end of the first curve in green, make an other curve downwards to the left and walk again round the preceding curves.
Thus I could continue any desired. There must be left on the right side, however, always two free curve ends. With that the double spiral would be finished inside the Wunderkreis.

Step 4

Step 4

Step 4: Now I must add at least three semi-circular curves round the previous lines.
If I want to have a bigger labyrinth, I can add more lines in pairs. There must however be an odd number of curves.
In our example we now have on the left side three free line ends, and on the right side five.

Step 5

Step 5

Step 5: Now I connect on every side the innermost and the outmost lying free line in such a manner that in between an access is possible. This is to be continued (here only on the right side) so long as on every side only one single line end is left.

Step 6

Step 6

Step 6: The both on every side lying free line ends are extended forwards. They represent the both lower turning points.
The labyrinth is finished.

Finally we will check out if the drawing is correct. We go in between the lines, turn to the right or to the left and must come again to the starting point. If not, something must be wrong.

Best try it out yourself, with a pencil on a sheet of paper. Wishing you success.

Among the Wunderkreise there are some variations:

  • Some with two entries like the Zeiden Wunderkreis
  • Some with one access, but a bifurcation such as the Russian Babylons and the examples of Kaufbeuren or Eberswalde
  • Some with a nearly perfect double spiral like the Zeiden Wunderkreis
  • Some with a “pulled apart” double spiral such as the Russian Babylons, the example of Eberswalde and some Swedish and Finnish examples

The Babylonian Wunderkreis

Wunderkreise are compound labyrinths which are constructed from curves around different central points. Both lower turning points are proper for the “labyrinthine” circuits, the ones in the middle for the double spiral.
The double spiral in the Zeiden Wunderkreis is made from two centres lying side by side, and with it a total of only four centres the whole Wunderkreis can be constructed.

Here a Swedish example with a pulled apart double spiral from the book of Hermann Kern:

A geometrically correct construction for a Wunderkreis with pulled apart double spiral requires more centres. Thus I receive for the Russian Babylons a total of six centres.

A sort of prototype with the dimension between axes of 1 m should serve as example. All values are thereby scaleable and differently big labyrinths can be constructed.

Best of all one begins by defining M1. After that one determines the direction of the perpendicular bisectors of the sides, and then constructs step by step the remaining mid points M2 to M6 through building the intersection of the triangle sides from two known points. All thereto necessary measurements are contained in the drawing.

The radii refer in each case to the middle axis of the boundary lines. The way runs between these boundary lines and, hence, is the empty space between these lines.

The Babylons are surely related to the widespread Troy Towns of the European North. However, they look a little bit different.
Directly after the entrance there is a bifurcation and therefore it is possible to go on in two directions. And then often there is no real middle, but rather you are headed back in a double spiral.

However, how could they have developed?
Numerous stone labyrinths have survived down to the present day in Fennoscandia. The Babylons are to be found particularly in the eastern area, from Finland up to the Russian Kola Peninsula. Often they are situated near the coast and on islands. The natives of Northern Europe, the Sami, settled here. It is possible that the Babylons deal with the traditional Sami religion.
They have presumably originated from the 13th century on until our times. And they were built in the same way: With stones fist-sized to head-sized laid down on the ground.

However, why do the Babylons look different and do not follow the well-known seed pattern with cross, angles and four dots? Much Scandinavian Troy Towns have eleven circuits and have been laid after the enlarged seed pattern.

The 11-circuit Cretan (Classical) labyrinth with the seed pattern of the cross, the four double angles and the four dots

The 11-circuit Cretan (Classical) labyrinth with the seed pattern of the cross, the four double angles and the four dots, on the right in a round shape

Thereby divergences and variations appeared. This can happen quite easily through this construction method.
Thus there are Swedish Troy Towns with the open cross which enables to take two directions to reach the middle, and to organise a race, e.g. This is why these also often are called “Jungfrudans” or “Jungfruringen”.

In the seed pattern for this labyrinth double angles only were used in the lower area. So we have 9 circuits.

Here the layout for a 11-circuit labyrinth:

In the report of Budovskiy I found a graphics (from 1973?) by Prof. Kuratov who has carried out a division of labyrinths and wanted probably show how the Babylon developed (see the sketched line in the graphics).

The table of Prof. Kuratov

The table of Prof. Kuratov

In the first column a sort of principle is to be seen. As first the whole Cretan labyrinth. In the second the left-handed spiral, in the third the right-handed spiral, then the double spiral and below circles.
In row Ia we see the Cretan type in different variations.
In row Ib the open cross and a decreasing middle.
In row II a right-handed spiral and the faulty stone setting discovered by Karl Ernst von Baer (1792 – 1876) in 1838 on the island of Wiehr.
In row III the Babylon with the double spiral.
In row IV some multiple-arm labyrinths which remind of the medieval labyrinths.

The open cross occurs several times under the Scandinavian labyrinths. Besides, the empty middle sometimes becomes smaller and then even slides under the two upper turning points. Finally, it is only indicated and then left out completely.

The drawing of John Kraft shows this:

I have found in a report about the Babylons on WeirdRussia, beside numerous photos, also this graphic :

The middle exists next to nothing. It is rather a niche or a widening of the way. In this area small stone heaps are sometimes stacked up. Should they show the gate to the underworld or the belly of the snake? The ends of the boundary lines are thickened. This is quite easy to make with some more stones.
The labyrinth has changed its meaning, with this its appearance and became the walk-through labyrinth.

Here the layout in geometrically correct form:

 

Babylon Solovki

Presumably most of the Babylons correspond to this shape.

On this photo one can recognise very well the alignment.

There is a graphic with a little “rounder” double spiral in the table of Prof. Kuratov and in Vinogradov’s report which I have still shown in my last post (see below).

There are  obviously some among the Finnish stone settings which look rather so.

According to most of the photos the Babylons doesn’t look exactly like this. The entrance is narrower and has a short straight piece.

Actually, one must consider them as a Wunderkreis. Even if they don’t have such a perfect double spiral like the Zeiden Wunderkreis. The Wunderkreise of Kaufbeuren or Eberswalde matches more likely the Babylons.

How could one call this type? In the last post I had suggested: Babylonian Wunderkreis. However, now I tend rather to Sami Wunderkreis because it developed in the cultural area of the Sami and probably was used in the cult of the dead.

According to Wikipedia there are in all about 35 labyrinths in the Solovetsky Islands in the Onega Bay of the White Sea in the  Arkhangelsk Oblast (Russia), about 500 km to the north of St. Petersburg and 150 km to the south of the polar circle.

How old are they, who has built them, what was the purpose? There are many speculations about that (see the Further Links below). I do not want to take part in it.
I only want to find out how they look like, which type of labyrinth they are. I have found enough indications. There are several photos which reveal a part of the labyrinths quite well, unfortunately, not completely.

On the Internet I have found the following graphics from a book published in 1927 by Nikolai Vinogradov (historian, ethnologist and folklorist, 1876 – 1938).

In Hermann Kern’s book “Labyrinths” I have found the photo of a petroglyph on the island Skarv in the Stockholm archipelago (Sweden), presumably from the 18th/19th century.

Compared to the graphics above the labyrinth is mirrored and the double spiral has a circuit less.

The labyrinths, called Babylons in the local dialect, have been made in the same way as the Scandinavian Troy Towns, probably at the same time and presumably served similar purposes.
Nevertheless, the layout is completely different. There are none of the well-known 11- or 15-circuit Cretan labyrinths which can be made from the enlarged seed pattern.

They belong to the walk-through labyrinths. These have a double spiral in the middle and labyrinthine circuits round two turning points. They can have two accesses or only one, however, with a bifurcation.

The hints, the Babylons could be seen as part of a cult of the dead and would show two snakes winding into each other, well explain the figure. They could also have been put on as a sort of piece of art.

There appear two spirals interlocking into each other. In a geometrical figure with semicircles around different centres they can be constructed as follows:

Blue and red spirals

Blue and red spirals

Both lines can be drawn well in one go and freehand: You will begin in the middle, turn to the right, circling once around, then in a larger turn outwardly from the right side to the left, from there inwards back to the right side. The red line ends her, the blue returns one more time to the left, circling inwards.
When you know how to draw each line, try to draw one in the other. Best begin with the blue line and leave enough space between the lines. Then put the red line in between.
That sounds complex, and it is. But best of all try several times with a pencil on a sheet of paper.

The result should look like thus:

The red spiral inside the blue one

The red spiral inside the blue one

For a labyrinth laid of stones these semicircular or elliptical curves can relatively simple be realised.

Best of all one starts in the middle. There one can arrange most easily the thickening of the ends and the interpieces. Then the remaining lines follow in steady distances.

Step 1 and 2

Step 1 and 2

One makes three semicircles downwards (step 1), and four semicircles upwards (step 2). Thus the double spiral in the middle is built.

Step 3 and 4

Step 3 and 4

Then I add five semicircles on top (step 3). There are five free ends on the left side, and seven on the right. These I elongate to the sloped line at right and at left (step 4).

Step 5 and 6

Step 5 and 6

In step 5 I connect both outermost free ends on the left and on the right side so with each other that in the middle a gap remains for the entrance. In step 6 the remaining free ends are connected parallel to the curves just made before. The innermost free end on each side will be the turning point.

It is noteworthy that the limitation lines do not overlap like they doe in the Cretan labyrinth. In spite of the bifurcation the way through the whole figure is unequivocal and follows the typical “labyrinthine” rhythm.

The construction elements

The construction elements

Even if the Babylons were not put on so geometrically precisely, nevertheless, these geometrical features show the essential internal structure and let them count to the Wunderkreise. I would like to call them Babylonian Wunderkreise to discern them from the Wunderkreise with two accesses side by side like we see that in the Zeidner Wunderkreis.

The Babylons are related to the Babylonian Labyrinths through the double spiral in the middle and the unequivocal way that leads to it, even if there are two opposite entrances.

This is what a Baltic Wheel looks like:

The Baltic Wheel

The Baltic Wheel

It has circuits which run primarily about two turning points. The middle is empty, however, it has a second, short way to leave it directly. Thereby we also have two entries which are separated by a spoon-like formed part.
Historical examples are very rare. In Germany there is the Rad in der Eilenriede at the town park of Hannover. Otherwise we only know this type from literature.

In the previous articles I have dealt with the Wunderkreis. Besides, a certain resemblance between both these types has also struck me. Though both have two entries they are still different types. In what way are they different now?

The Wunderkreis

The Wunderkreis

The labyrinthine circuits are disposed around turning points which are arranged in a triangle. In the middle we have a double spiral (the circuits A, B, C) through which we leave the Wunderkreis. We have a walk-through labyrinth lying ahead of us.

The Baltic Wheel has a big, empty middle and consequently contains no double spiral. However, there is also the second access (or exit). If I leave out the circuits for the double spiral, I shall nearly get the  Baltic Wheel.

The intermediate stage

The intermediate stage

The remaining circuits are the same. Also the path sequence is the same. This shows the close relationship between the two labyrinth types.

Now I add a middle section formed from arcs between the two entrances and will thus receive a complete Baltic Wheel.

The Baltic Wheel

The Baltic Wheel

The Baltic Wheel can exist of a varied number of circuits. These can be added the same way as in the Wunderkreis (see related posts below).

Other design elements can also be added, such as an additional circuit around the whole Baltic Wheel.

Some years ago I had already published construction instructions for the Baltic Wheel. It looked a little bit different. The construction developed now seems easier to me and I like it better.

If I have fixed the number of the circuits for a Baltic Wheel, I can also begin with the base line of the triangle (between M3 and M4) and then determine the centre M1.

The construction has a dimension between axes of 1 m and therefore allows to scale it easier.

The previous post was more concerned with the geometry and the mathematically correct construction of the Wunderkreis in general.

Here is an example of how you can make it less theoretically. Denny Dyke from Circles in the Sand often creates double spirals and the Wunderkreis in his Dream Fields on the beach of Oregon. Denny Dyke has kindly shown me his method.
In the following photos it is explained.

Freehand he scratches the lines in the sand. Hence, the way runs between the lines. The double spiral has three arcs, the surrounding labyrinth has five circuits.

Step 1

Step 1

Denny begins with the lower part of the double spiral and draws three semicircles. On the left he adds two lines and the turning point, on the right there are three lines and the turning point (step 1).

Step 2

Step 2

Now he scratches three semicircles for the upper part of the double spiral. The first semicircle begins in the middle of the innermost lower semicircle (step 2).

Step 3

Step 3

All the other curves are drawn in parallel and equal distance to this arc by connecting all free ends of the existing lines and the turning points. Just the way we do it in the Classical labyrinth. We begin on top and draw four lines on the left side around the double spiral to the right side (step 3).

Step 4

Step 4

In the same way the two free lines below are connected together (step 4). Having done this the Wunderkreis has quite been completed.

The open lower middle section contains the two entries of the Wunderkreis. On the left side we enter the labyrinthine circuits. On the right side we have the exit out of the double spiral.

The completed Wunderkreis

Denny has marked both accesses and has separated them through the “shoehorn” known from the Baltic wheel.

A Wunderkreis is a double spiral, surrounded by a simple labyrinth with two turning points.

We begin in the centre with the double spiral. One  semicircle below and one semicircle above the horizontal line would suffice as a minimum. Many more semicircles could be added to enlarge the double spiral. Here we make three arcs which we name A, B and C. The lower ones are drawn around M1 as the centre, the upper ones are arranged around M2 as the centre and shifted to the right.

Step 1

Step 1

Then we add three arcs on the left side. They are drawn in a triangular sector around the midpoint M1. We number the circuits from the outside with 1, 2 and 3. Circuit 3 will finally form the entrance.
The turning and midpoint M3 for the lower semicircle lies concentric between the both external circuits 1 and 2.

Step 2

Step 2

Now we go to the right side. Here two arcs more than on the left side are necessary, that means a total of five. Again we number the circuits from the outside inwards from 1 to 5. The circuit 5 will later lead to the exit.
The turning point M4 lies concentric between the four circuits 1 to 4. In the lower middle section two semicircles are traced around that midpoint M4.

Step 3

Step 3

Now the upper semicircles are completed around the midpoint M2. There are four semicircles (and circuits) more on each side than at the beginning.

Step 4

Step 4

The Wunderkreis is usually entered through the labyrinthine circuits on circuit 3 and left through the double spiral on circuit 5. The path sequence then is as follows: 3-2-1-4-C-B-A-A-B-C-5.
The path sequence 3-2-1-4 forms the basis of the meander, as connoisseurs know, as in the Knossos labyrinth.


Now we choose more circuits and apply the abovementioned principles to the construction. Through that Wunderkreise with a varied number of circuits can be generated. We can add circuits to the double spiral one by one, to the labyrinth we have to do it in pairs.
On the right side two circuits more are necessary than on the left. The lower turning points (M3 and M4) must lie concentric between the even-numbered left or right circuits. In the following example we have 6 circuits on the left and 8 on the right side.

If we know how many circuits for a Wunderkreis we want, we can lay both lower turning points on a line and determine the middle for the double spiral (M1) in a triangle. Entrance and exit can also be arranged  side by side without any space.

Nevertheless we can begin, while marking out, with the definition of the middle M1 and also determine the adjustment of the main axis (vertical line). The remaining centres M3 and M4 can afterwards be fixed in that triangle.

The main dimensions

The main dimensions

Best of all we consider the measurements as units, so either “metre” or “yard” or “step width” or something similar. Then we can also scale all dimensions.
The smallest radius begins with 1 unit and then gradually grows by 1 from arc to arc. Then the biggest radius has 12 units. The boundary lines add themselves on 407 units, the whole way through the Wunderkreis reaches 362 units.

The completed Wunderkreis

The completed Wunderkreis

In this example the Wunderkreis has four circuits more than in the other at the top of the page and no space between entrance and exit. This area is formed quite differently in the historical Wunderkreise. Sometimes the paths are joined together, sometimes they run apart.
