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. |

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. |
