Reconstruction of the
Silbury Hill 31-05-2010 formation

1. Draw a circle. Draw and extend the horizontal and vertical centerlines.

2. Create a "Flower-of-Life"-pattern, by copying circle 1 six times, the first to the righthand intersection of circle 1 and the horizontal centerline, the others to the upper/next intersection of circle 1 and the last copied circle, as shown.

3. Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 1 and its lefthand intersection with the horizontal centerline.

4. Copy circle 3 six times, to the outer mutual intersections of circles 2.

5. Construct two inscribed equilateral triangles of circle 1, one pointing to the left, one to the right.

6. Construct the circle passing through the mutual intersections of triangles 5.

7. Construct two inscribed equilateral triangles of circle 6, one pointing up, one pointing down.

8. Construct the inscribed circle of triangles 7.

9. Construct a circle concentric to circle 1, tangent to the rightmost circle 2 at the righthand side.

10. Construct the circumscribed hexagon (regular six-sided polygon) of circle 9, pointing up.

11. Construct the circumscribed circle of hexagon 10.

12. Circles 1, 2, 4, 8 and 11, are used for the final reconstruction.

13. Remove all parts not present in the formation itself.
