Reconstruction of the 2007 Winterbourne Monkton formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed pentagon (regular 5-sided polygon) of circle 1, pointing up. |
| 3. |
| Construct the inscribed circle of pentagon 2. |
| 4. |
| Construct the inscribed pentagon of circle 3, pointing up. |
| 5. |
| Construct the inscribed pentagon of (the inscribed circle of) pentagon 4, pointing down. |
| 6. |
| Construct the inscribed circle of pentagon 5. |
| 7. |
| Draw the diagonal of pentagon 2, from the top to the lower lefthand angular point. |
| 8. |
| Draw the diagonal of pentagon 2, from the top to the lower righthand angular point. |
| 9. |
| Finish the inscribed pentagram of pentagon 2 by drawing the other diagonals. |
| 10. |
| Construct the circumscribed circle of the enclosed pentagon of pentagram 7-8-9. |
| 11. |
| Copy circle 10 to the righthand intersection of circle 1 and the horizontal centerline. |
| 12. |
| Construct a circle concentric to circle 1, tangent to circle 11 at the righthand side. Move it (copy and delete original) to the intersection of line 7 and the horizontal centerline. |
| 13. |
| Copy circle 6 to the righthand intersection of circle 11 and the horizontal centerline. |
| 14. |
| Construct a circle concentric to circle 1, tangent to circle 13 at the righthand side. |
| 15. |
| Copy circle 10 to the righthand intersection of circle 13 and the horizontal centerline. |
| 16. |
| Construct a circle concentric to circle 1, tangent to circle 15 at the righthand side. Move it to the intersection of line 8 and the horizontal centerline. |
| 17. |
| Copy circle 6 to the righthand intersection of circle 15 and the horizontal centerline. |
| 18. |
| Construct a circle concentric to circle 1, tangent to circle 17 at the righthand side. |
| 19. |
| Copy circle 10 to the center of circle 17. |
| 20. |
| Copy circle 6 to the righthand intersection of circle 19 and the horizontal centerline. |
| 21. |
| Construct a circle concentric to circle 1, tangent to circle 20 at the righthand side. Move it to the intersection of line 7 and the horizontal centerline. |
| 22. |
| Copy circle 6 to the righthand intersection of circle 20 and the horizontal centerline. |
| 23. |
| Construct a circle concentric to circle 1, tangent to circle 22 at the righthand side. |
| 24. |
| Copy circle 10 to the center of circle 22. Move it to its own righthand intersection with the horizontal centerline. |
| 25. |
| Construct a circle concentric to circle 1, tangent to circle 24 at the righthand side. |
| 26. |
| Only circles 1, 3, 6, 10, 12, 14, 16, 18, 21, 23 and 25 are needed for the final reconstruction. |
| 27. |
| Colour all areas of standing... |
| 28. |
| ...or of flattened crop, and finish the reconstruction of the 2007 Winterbourne Monkton formation. |
| 29. |
| The final result, matched with the aerial image. |
