The seed patterns of the heart labyrinth by Mario Höhn were even more difficult to identify for me than those of the Nîmes labyrinth.
As fig. 1 shows, what is special about this labyrinth is not so much its heart-shaped form. This alone would not much affect the seed pattern. Very special, however, is that the circuits 7 and 6 are restricted to the first (right) half of the heart. Despite this, the labyrinth looks symmetric. This is because an additional circuit in the form of a turning loop was added in the second (left) half. This fills the space that was left empty by the missing circuits 7 and 6.
Therefore, two variations are made to the seed pattern. This is shown in fig. 2:
- First, the turn from the 7th to the 6th circuit is moved from the 3rd to the 2nd quadrant (A). This turn in the seed pattern for the walls (blue) is marked by an angle or an arc and a dot placed within it. In the seed pattern for the Ariadne’s Thread (red) it is designed as an arc. Therefore, these turns of the pathway are doubled in the second quadrant, the first is embedded between the arms of the central cross, the second lies mirrored somewhere opposite to it.
- In the right heart chamber the pathway reaches the 7th circuit coming from the 4th circuit. This is as usual in the Cretan type of labyrinth. But then, without leaving the second quadrant, it turns to the 6th and again to the 5th circuit. Only this circuit leads to the left heart chamber. And there, the path does not reach the center from below, but spirals in before it branches to the turning loop, the additional 8th circuit. This is marked in the figure by the red circle, which indicates the situation of the turning loop and the black bullet indicating the center of the labyrinth. This course of the pathway causes an additional spiralling wall to be laid-out in the left heart chamber. These additional modifications in the area of the center have to be added to the seed pattern (B).
Since these modifications cause strong biases to the seed pattern, I have indicated in fig. 3 which ends have to be connected to each other in order to complete the seed patterns to the whole labyrinth. As usual, completion begins with the two ends that connect to the innermost wall / circuit. I numbered these ends with 1. We then continue following the ascending numbers and thus proceeding from the inside out. Since circuits 7 and 6 are restricted to the first half of the labyrinth and due to the additional features around the center, the two innermost circuits / three innermost walls are not connected with an arc around the center. Only the five outer circuits are connected around the center.
This variant of the Cretan type labyrinth causes variations to the seed pattern such that it misses its original purpose. The purpose of a seed pattern is, that it provides a simple graph, that can be easily kept in mind and completed straightforward to the whole labyrinth.
