2008 Avebury Down formation
|
Reconstruction of the 2008 Avebury Down formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the circumscribed square of circle 1, sides horizontal and vertical. |
| 3. |
| Construct the circumscribed circle of square 2. |
| 4. |
| Construct the circumscribed square of circle 3, sides horizontal and vertical. |
| 5. |
| Construct the circumscribed circle of square 4. |
| 6. |
| Construct the circumscribed square of circle 5, sides horizontal and vertical. |
| 7. |
| Construct the circumscribed circle of square 6. |
| 8. |
| Copy circle 7 to the righthand intersection of circle 5 and the horizontal centerline. Move this circle (copy and delete original) to its own corresponding intersection. |
| 9. |
| Copy circle 3 to the righthand intersection of circle 8 and the horizontal centerline. Move this circle to its own corresponding intersection. |
| 10. |
| Construct a circle concentric to circle 1, passing through the center of circle 9. |
| 11. |
| Copy circle 3 two times, to the upper and lefthand intersections of circle 10 with the horizontal and vertical centerlines. |
| 12. |
| Copy circle 10 to its own lower intersection with the vertical centerline. |
| 13. |
| Draw the connecting line between the intersections of circles 10 and 12. |
| 14. |
| Copy circle 5 to the intersection of line 13 and the vertical centerline. |
| 15. |
| Copy circles 5 and 14 as a whole two times, from the center of circle 5 to the lower intersections of circles 10 and 12 with the vertical centerline. |
| 16. |
| Construct a circle concentric to circle 9, passing through the center of circle 8. |
| 17. |
| Copy circle 16 two times, to the centers of circles 11. |
| 18. |
| Copy circle 1 six times, to the intersections of circles 16 and 17 with the horizontal and vertical centerlines. |
| 19. |
| Construct a circle concentric to circle 9, tangent to circle 12 at the upper righthand side. |
| 20. |
| Copy circle 19 two times, to the centers of circles 11. |
| 21. |
| Construct a circle centered at the righthand intersection of circle 10 and the horizontal centerline, tangent to circle 10 at the opposite side. |
| 22. |
| Copy circle 21 two times, to the lefthand intersection of circle 10 and the horizontal centerline, and to the lower intersection of circle 10 and the vertical centerline. |
| 23. |
| Copy circle 1 six times, to the intersections of circles 19 and 20 with circles 21 and 22. |
| 24. |
| Draw two lines, one between the centers of the uppermost circle 18 and the lowermost circle 15, the other between the centers of the leftmost and rightmost circles 18. |
| 25. |
| Circles 5, 9, 11, 14, 15, 18, 21, 22 and 23, and lines 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 plants, and finish the reconstruction of the 2008 Avebury Down formation. |
| 29. |
| The final result, matched with the aerial image. |
