2013 Silbury Hill formation
|
Reconstruction of the 2013 Silbury Hill formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed hexagon (regular 6-sided polygon) of circle 1, pointing to the right. |
| 3. |
| Construct a circle centered at the lower intersection of circle 1 and the vertical centerline, passing through the lower angular points of hexagon 2. |
| 4. |
| Construct four circles centered at the upper and lower angular points of hexagon 2, all passing through the center of circle 1. |
| 5. |
| Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 1 and its righthand intersection with the horizontal centerline. |
| 6. |
| Copy circle 5 to the center of circle 1. |
| 7. |
| Construct the circumscribed hexagon of circle 6, pointing up. |
| 8. |
| Construct the circumscribed circle of hexagon 7. |
| 9. |
| Construct a "two-points" circle between the righthand intersections of circles 1 and 8 with the horizontal centerline. |
| 10. |
| Construct the vertical centerline of circle 9. |
| 11. |
| Construct a circle concentric to circle 1, tangent to line 10. |
| 12. |
| Construct a circle concentric to circle 1, passing through the intersections of circle 9 and centerline 10. |
| 13. |
| Construct a circle concentric to circle 9, tangent to circle 12 at the righthand side. |
| 14. |
| Copy circle 13 to the righthand intersection of circle 1 and the horizontal centerline. |
| 15. |
| Construct two circles concentric to circle 1, tangent to circle 14 at both sides. |
| 16. |
| Copy circle 13 to the righthand intersection of circle 8 and the horizontal centerline. |
| 17. |
| Construct a circle concentric to circle 1, tangent to circle 16 at the righthand side. |
| 18. |
| Copy circle 9 to the center of circle 1. |
| 19. |
| Copy circle 13 to the righthand intersection of circle 18 and the horizontal centerline. |
| 20. |
| Construct a circle concentric to circle 1, tangent to circle 19 at the righthand side. |
| 21. |
| Copy circle 13 to the center of circle 1. |
| 22. |
| Construct four circles concentric to circles 4, tangent to circle 21, each at the near side. |
| 23. |
| Construct a circle concentric to the lower righthand circle 4, passing through the lefthand intersection of circle 8 and the horizontal centerline. |
| 24. |
| Copy circle 23 three times, to the centers of the other circles 4. |
| 25. |
| Circles 3, 4, 11, 12, 15, 17, 20, 22, 23 and 24, are used for the final reconstruction. |
| 26. |
| Remove all parts not visible within the formation itself. |
| 27. |
| Colour all areas corresponding to standing... |
| 28. |
| ...or to flattened crop, and finish the reconstruction of the 2013 Silbury Hill formation. |
| 29. |
| The final result, matched with the aerial image. |
