Reconstruction of the
Etchilhampton Hill 15-08-2008 formation

1. Draw a circle. Draw and extend the horizontal and vertical centerlines.

2. Construct a "two-points" circle, defined by the end-points of a centerline (diameter), between the center of circle 1 and its upper intersection with the vertical centerline.

3. Construct a "two-points" circle between the centers of circles 1 and 2.

4. Copy circle 3 to the center of circle 1.

5. Construct a circle concentric to circle 2, passing through the intersections of circle 4 and the horizontal centerline.

6. Construct a "two-points" circle between the lower intersections of circles 2 and 5 with the vertical centerline.

7. Construct a circle concentric to circle 2, passing through the center of circle 6.

8. Construct a circle concentric to circle 1, tangent to circle 7 at the upper side.

9. Copy circle 6 to the upper intersection of circle 5 and the vertical centerline.

10. Construct a circle concentric to circle 1, tangent to circle 9 at the upper side.

11. Construct a circle concentric to circle 2, tangent to circle 9 at the upper side.

12. Copy circle 6 to the upper intersection of circle 11 and the vertical centerline.

13. Construct a circle concentric to circle 2, tangent to circle 12 at the upper side.

14. Copy circle 6 to the upper intersection of circle 13 and the vertical centerline.

16. Copy circle 6 to the upper intersection of circle 4 and the vertical centerline.

17. Construct a circle concentric to circle 1, tangent to circle 16 at the upper side.

18. Copy circle 3 four times, to the intersections of circle 1 with both, the horizontal and vertical centerlines.

19. Copy circle 1 to its upper intersection with the vertical centerline.

20. Construct a circle concentric to circle 1, tangent to circle 19 at the upper side.

21. Copy circle 3 four times, to the intersections of circle 20 with both, the horizontal and vertical centerlines.

22. Copy circles 1 and 20 to the lower intersection of circle 20 and the vertical centerline.

23. Copy circle 3 to the lower intersection of the inner circle 22 (copied circle 1) and the vertical centerline.

24. Copy circle 3 to the lower intersection of the outer circle 22 (copied circle 20) and the vertical centerline.

25. Copy circles 2 and 7 to the lower intersection of circle 4 and the vertical centerline. Use this centerline to cut these circles into two halves and remove the lefthand halves.

26. Copy half circles 25 three times, to the other intersections of circle 4 with the horizontal and vertical centerlines, while rotating them 90°, 180° and 270° respectively with respect to the center of circle 1.

27. Copy circles 2, 7, 5 and 13 to the upper intersection of lower circle 18 and the vertical centerline. Use this centerline to cut these circles into two halves and remove the righthand halves.

28. Copy half circles 27 three times, to corresponding intersections of the other circles 18 with the horizontal and vertical centerlines, while rotating them 90°, 180° and 270° respectively with respect to the center of circle 1, as shown.

29. Copy circles 2, 7, 5 and 13 to the lower intersection of lower circle 18 and the vertical centerline. Use this centerline to cut these circles into two halves and remove the lefthand halves.

30. Copy half circles 29 three times, to corresponding intersections of the other circles 18 with the horizontal and vertical centerlines, while rotating them 90°, 180° and 270° respectively with respect to the center of circle 1, as shown.

31. Copy half circles 27 and 29 as a whole two times, from the lower intersection of circle 4 and the vertical centerline, to the corresponding intersections of lower circles 18 and 21, as shown.

32. Copy circles 2, 7, 5 and 13 four times, to the inward intersections (closest to the center of circle 1) of lefthand, upper and righthand circles 21 and circle 24 with the horizontal and vertical centerlines, as shown.

33. (For clarity, the results of steps 27, 28, 29, 30 and 31 have been removed temporarily)

Copy circles 7, 5, 11 and 15 to the upper intersection of lower circle 18 and the vertical centerline. Use this centerline to cut these circles into two halves and remove the lefthand halves.

34. Copy half circles 33 three times, to corresponding intersections of the other circles 18 with the horizontal and vertical centerlines, while rotating them 90°, 180° and 270° respectively with respect to the center of circle 1, as shown.

35. Copy circles 7, 5, 11 and 15 to the lower intersection of lower circle 18 and the vertical centerline. Use this centerline to cut these circles into two halves and remove the righthand halves.

36. Copy half circles 35 three times, to corresponding intersections of the other circles 18 with the horizontal and vertical centerlines, while rotating them 90°, 180° and 270° respectively with respect to the center of circle 1, as shown.

37. Copy half circles 33 and 35 as a whole two times, from the lower intersection of circle 4 and the vertical centerline, to the corresponding intersections of lower circles 18 and 21, as shown.

38. (Half) circles 1, 8, 10, 17, 18, 21, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36 and 37, are used for the final reconstruction.

39. Remove all parts not visible within the formation itself.
