Reconstruction of the 2005 Avebury Trusloe formation | ||
| 1. |
| Draw a circle. Draw and extend the horizontal and vertical centerlines. |
| 2. |
| Construct the inscribed equilateral triangle of circle 1, pointing to the right. |
| 3. |
| Construct the inscribed circle of triangle 2. |
| 4. |
| Construct three circles, each centered at a different angular point of triangle 2, each passing through the adjacent intersections (tangent points) of circle 3 and triangle 2. |
| 5. |
| Copy and mirror each circle 4, relative to the side of triangle 2 opposite to it. |
| 6. |
| Copy and mirror the two righthand circles 5, relative to the lefthand side of triangle 2. |
| 7. |
| Draw the connecting line between the centers of the two righthand circles 5. |
| 8. |
| Copy and mirror the two lefthand circles 4, relative to line 7. |
| 9. |
| Draw the connecting line between the centers of upper circles 4 and 5. |
| 10. |
| Copy and mirror righthand circle 4, relative to line 9. |
| 11. |
| Draw the connecting line between the centers of lower circles 4 and 5. |
| 12. |
| Copy and mirror righthand circle 4, relative to line 11. |
| 13. |
| Copy and mirror circles 4, 5, 6, 8, 10 and 12, relative to the vertical centerline. |
| 14. |
| Construct the inscribed equilateral triangle of circle 12, pointing to the left. |
| 15. |
| Copy triangle 14 eleven times, to the centers of circles 4, 5, 6, 8 and 10 (that means, constructing the left-pointing inscribed equilateral triangle of each of these circles). |
| 16. |
| Construct the inscribed equilateral triangle of lowest circle 13, pointing to the right. |
| 17. |
| Copy triangle 16 eleven times, to the centers of all other circles 13. |
| 18. |
| Draw the connecting line between the lefthand angular point of triangle 14 and the righthand angular point of triangle 16. |
| 19. |
| Construct a circle, centered at the intersection of the righthand side of triangle 14 and line 18, tangent to lowest circle 13 at the lefthand side. |
| 20. |
| Copy circle 19 to the center of circle 12. |
| 21. |
| Copy circle 20 eleven times, to the centers of circles 4, 5, 6, 8 and 10. |
| 22. |
| Construct the circumscribed equilateral triangle of circle 20, pointing to the left. |
| 23. |
| Copy triangle 22 eleven times, to the centers of circles 21 (that means, constructing the left-pointing circumscribed equilateral triangle of all circles 21). |
| 24. |
| Copy circle 20 to the center of lowest circle 13. |
| 25. |
| Copy circle 24 eleven times, to the centers of all other circles 13. |
| 26. |
| Construct the circumscribed equilateral triangle of circle 24, pointing to the right. |
| 27. |
| Copy triangle 26 eleven times, to the centers of circles 25. |
| 28. |
| Construct the inscribed equilateral triangle of circle 20, pointing to the left. |
| 29. |
| Copy triangle 28 eleven times, to the centers of circles 21. |
| 30. |
| Extend the upper lefthand and righthand sides of upper triangles 15 and 17, respectively, until intersection. |
| 31. |
| Construct a circle concentric to circle 1, passing through the intersection of lines 30. |
| 32. |
| Construct the circumscribed hexagon (regular 6-sided polygon) of circle 31, pointing to the right. |
| 33. |
| Triangles 14, 15, 16, 17, 22, 23, 26, 27, 28 and 29, and hexagon 32, together, make up the constituent parts of the reconstruction. |
| 34. |
| Colour the areas, corresponding to standing... |
| 35. |
| ...or to flattened crop, to make the reconstruction of the 2005 Avebury Trusloe formation complete. |
| 36. |
| The final result, matched with the aerial image. |
