Reconstruction of the 2017 Battlesbury Hill formation | ||
1. | Draw a circle. Draw the horizontal and vertical centerlines. | |
2. | Construct the inscribed square of circle 1, with the sides parallel to the horizontal and vertical centerlines. | |
3. | Construct the inscribed circle of square 2. | |
4. | Construct the inscribed square of circle 3, pointing to the right. | |
5. | Construct the inscribed circle of square 4. | |
6. | Construct a circle centered at the upper righthand angular point of square 2, tangent to circle 5 at the upper righthand side. | |
7. | Copy circle 6 three times, to the other angular points of square 2. | |
8. | Construct a circle concentric to circle 1, passing through the lower intersection of square 2 and circle 6. | |
9. | Construct a circle concentric to circle 6, tangent to circle 8 at the upper righthand side. | |
10. | Copy circle 9 three times, to the centers of circles 7. | |
11. | Construct the circumscribed square of circle 8, with the sides horizontally and vertically. | |
12. | Construct a "two-points" circle (defined by the two end-points of a centerline) between the upper righthand angular points of squares 2 and 11. See detail. | |
13. | Repeat step 12 three times, with respect to the other angular points of squares 2 and 11. | |
14. | Construct two pairs of parallel lines, parallel to the diagonals of square 11, tangent to circles 12 and 13 at both sides. See detail. | |
15. | Construct a circle centered at the righthand intersection of circle 1 and the horizontal centerline, passing through the upper lefthand intersection of square 11 and circle 12. See detail. | |
16. | Copy circle 15 to the center of circle 1. | |
17. | Construct a circle centered at the lefthand intersection of circles 6 and 8, tangent to circle 16 at the near side. | |
18. | Construct a circle concentric to circle 6, tangent to circle 17 at the lefthand side. | |
19. | Copy circle 18 three times, to the centers of circles 7. | |
20. | Draw the connecting line between the centers of circles 1 and 6. | |
21. | Construct a "two-points" circle between the intersections of circles 5 and 9 with line 20. | |
22. | Construct a circle concentric to circle 1, passing through the center of circle 21. | |
23. | Construct a circle concentric to circle 6, passing through the center of circle 21. | |
24. | Copy circle 17 to the lower righthand intersection of circles 21 and 22. | |
25. | Copy circle 17 to the upper lefthand intersection of circles 21 and 23. | |
26. | Copy circles 24 and 25 three times, by repeating steps (20, 21, 23,) 24, and 25, with respect to circles 7 in stead of circle 6, as shown. | |
27. | Circles 1, 5, 6, 7, 8, 9, 10, 16, 18, 19, 24, 25, and 26, and lines 14, are used for the final reconstruction. | |
28. | Remove all parts not visible within the formation itself. | |
29. | Colour all areas corresponding to standing... | |
30. | ...or to flattened crop, and finish the reconstruction of the 2017 Battlesbury Hill formation. | |
31. | The final result, matched with the aerial image. |
