There are so far hardly archaeoastronomical considerations of the historical labyrinths. Mechthild Meinike from Halle (Germany) made such investigations for the Troy Town of Steigra .
The area around Steigra is richly at early finds, in particular the sky disk of Nebra and the circle of Goseck provided headlines in the last years. This very day large archaeological excavations are accomplished nearby with many finds from the Bronze and Stone Ages.
The astronomical classification of the Troy Town by the adjustment of the azimuths on the surrounding topography, salient points, other early buildings, and water places however brought no substantial purchases, nor was it brought by the consideration of the moon extremes.
Mechthild Meinike computed the sunrise and sunset azimuths for the labyrinth at the solstices for the years 1500 B. C., 1700 A. C., and today. The values of the azimuths for the three used times lie together very closely. The values of 1500 B. C. are drawn on the illustration shown here .
The results are as follows: A line, which one draws through the center of the labyrinth, the small rhombus, and the entrance area, points to the sunset at summer solstice. In other words, if one stands in the center, the sun is setting down behind the entrance on summer solstice. When going into the labyrinth one has first the going down sun in the back, one comes thus from the going down sun.
If one stands in the center of the labyrinth at the time of the sunrise on winter solstice and looks towards the grave hill beside the labyrinth, then one looks into the rising sun.
Here the summary of the article (translated from German):
Concluding it can be stated that the Troy Town of Steigra has an adjustment on the sunset at summer solstice, if one looks from the center towards the entrance. The sunrise at winter solstice is just behind the grave hill. Thus the Troy Town hides a concrete reference to historically handed down sun stories of virgins, knights and dragons.
What does this mean now for the labyrinth-enthusiast?
As we do not know enough about the real age of the labyrinth of Steigra and its meaning or use, this is not a proof, that the adjustment to the sun played a role for the the building of the labyrinth. However, we can assume that a connection with the running of the sun could exist and from there also a relationship with the relevant historical tradition in myths, fairy tales and narrations could be given.
Further archaeoastronomical investigations in other old labyrinths would be desirable.
