Reconstruction of the 2003 Burderop Down formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed dodecagon (regular 12-sided polygon) of circle 1, pointing up. (The dodecagon can easily be constructed by two hexagons – regular 6-sided polygons –, one pointing up, one pointing to the right). |
| 3. |
| Construct the "flower of life" pattern, by copying circle 1 six times to every other angular-point of dodecagon 2, starting at the top. |
| 4. |
| Construct a second "flower of life" pattern in the same way as step 3, now starting at the right. |
| 5. |
| Construct a circle concentric to circle 1, tangent to circles 3 and 4 (at the outer sides). |
| 6. |
| Construct the inscribed dodecagon of circle 5, pointing up. |
| 7. |
| Copy circle 1 six times to every other angular-point of dodecagon 6, starting at the top. |
| 8. |
| Copy circle 1 six times to the tangent-points (intersections) of circles 7, as shown. |
| 9. |
| Construct a circle, centered at the rightmost angular-point of dodecagon 6, tangent to the two rightmost circles 3 at the near sides. |
| 10. |
| Copy circle 9 to the center of circle 1. |
| 11. |
| Construct the circumscribed dodecagon of circle 1, with the middle of the upper side coincident with the upper angular-point of dodecagon 2, as shown. |
| 12. |
| Construct the circumscribed circle of dodecagon 11. |
| 13. |
| Copy circle 12 six times, to the centers of circles 4. |
| 14. |
| Construct a circle, centered at the right angular-point of dodecagon 11 just above the horizontal centerline, tangent to the corresponding (near) side of dodecagon 2. |
| 15. |
| Copy circle 14 to the right intersection of circle 1 and the horizontal centerline. |
| 16. |
| Construct a circle concentric to circle 1, tangent to circle 15 at the far side. |
| 17. |
| Copy circle 16 six times, to the centers of circles 3. |
| 18. |
| Construct a small circle the centerline of which connects the two lower intersections of circles 12 and 16 with the vertical centerline. |
| 19. |
| Construct a circle concentric to the lower circle 7, passing through the center of circle 18, see detail. |
|
| ||
| 20. |
| Copy circle 19 six times, to the centers of circles 3. |
| 21. |
| Copy circle 19 five times, to the centers of the other circles 7. |
| 22. |
| Copy circle 19 again six times, to the centers of circles 8. |
| 23. |
| Circles 1, 3, 4, 7, 8, 10, 12, 13, 17, 19, 20, 21 and 22 make up all ingredients for the reconstruction. |
| 24. |
| Leave out all parts not visible in the formation. |
| 25. |
| All areas corresponding to standing... |
| 26. |
| ...or to flattened crop are coloured, which finishes the reconstruction of the 2003 Burderop Down formation. |
| 27. |
| The final result, matched with the aerial image. |
