Fieldwork
 
Behind the ruins on the left side of the village, I found a big open field. In that time of year, the field was hit by the sun for eight hours. In the following weeks, I spent my time there to understand the course of the sun.
 
With a compass, I looked where the sun rose behind the mountain and where it set again. I tied strings around the trees that were in line with east and west. I put one string perpendicular to the other. At noon the strings were in line with the highest point of the sun.
 
Four strings hung in the air. On top of them, I placed several sticks forming three times the same shape: one square inside another. When placing the sticks on the strings, the sticks found their position by their weight, laying on the strings as a suspension bridge.
 
When the sun reached its highest point, the sticks cast a shadow in the shape of a clear square. At both the beginning and end of the day the shadows were very crooked; it was almost impossible to recall a rectangular shape.
