Reconstruction of the
Avebury Stone Circle (2) 28-07-2002 formation

1. Draw 9 circles on a row horizontally, each passing through the center(s) of its neighbours. Draw the horizontal centerline of all 9, and the vertical centerline of the middle one.

2. Construct a circle concentric to middle circle 1, tangent to the first and last circles 1, at the far sides.

3. Remove all dashed circles 1, and retain the middle three, tangent to one another, as shown. Construct a circle centered at the right-hand intersection of middle circle 1 and the horizontal centerline, tangent to circle 2 at the right-hand side.

4. Construct a circle centered at the left-hand intersection of middle circle 1 and the horizontal centerline, tangent to circle 2 at the left-hand side.

5. Construct a circle concentric to circle 3, tangent to circle 4 at the right-hand side.

6. Construct a circle concentric to circle 4, tangent to circle 3 at the left-hand side.

7. Construct the circumscribed dodecagon (regular 12-sided polygon) of circle 2.

8. Construct the circumscribed circle of dodecagon 7.

9. Construct a circle concentric to middle circle 1, tangent to circle 3 at the left-hand side (and circle 4 at the right-hand side).

10. Construct the inscribed dodecagon of circle 9.

11. Construct the inscribed circle of dodecagon 10.

12. Construct a circle concentric to the (retained) right-hand circle 1, tangent to circle 11 at the near side.

13. Construct a (small) circle with its center at the right-hand intersection of the horizontal centerline and right-hand circle 1, tangent to circle 12 at the near side.

14. Construct a circle concentric to right-hand circle 1, tangent to circle 13 at the right-hand side.

15. Construct a circle with a diameter half that of circle 1.

16. Copy circle 15 2 times, one to the right-hand intersection of circle 14 and the horizontal centerline, the other one to the corresponding intersection of this copied circle itself. Retain only the last one.

17. Copy circle 13 to its right-hand intersection with the horizontal centerline, as shown here enlarged.

18. Construct a circle concentric to circle 16, tangent to circle 17 at the right-hand side.

19. Construct a circle centered at the right-hand intersection of circle 2 and the horizontal centerline, tangent to circle 8 at the near side.

20. Copy circle 19 to its left-hand intersection with the horizontal centerline.

21. Construct a circle with a diameter half that of circle 20.

22. Copy circle 21 to the center of circle 20.

23. Construct a circle centered at the horizontal centerline, tangent to circle 16 at the right-hand side, and tangent to circle 20 at the left-hand side.

24. Construct a circle with a diameter half that of circle 23.

25. Copy circle 24 to the center of circle 23.

26. Construct a line from the center of circle 16, perpendicular to the horizontal centerline, downto circle 3.

27. Construct a circle with a diameter half that of circle 18.

28. Copy circle 27 2 times, one to the intersection of circle 16 and line 26, the other one to the corresponding intersection of this copied circle itself. Retain only the last one.

29. Construct a circle concentric to circle 28, tangent to circle 18 at the lower side.

30. Copy circle 25 2 times, one to the lower intersection of circle 29 and line 26, the other one to the corresponding intersection of this copied circle itself. Retain only the last one.

31. Construct a circle concentric to circle 30, tangent to circle 28 at the lower side.

32. Copy circle 22 2 times, one to the lower intersection of circle 31 and line 26, the other one to the corresponding intersection of this copied circle itself. Retain only the last one.

33. Construct a circle concentric to middle circle 1, passing through the center of circle 23.

34. Construct a circle concentric to circle 23, tangent to circle 18 at the right-hand side.

35. Copy circle 25 2 times, one to the lower intersection of circles 33 and 34, the other one to the corresponding intersection of this copied circle itself. Retain only the last one.

36. Construct a circle concentric to circle 35, tangent to circle 23 at the lower side.

37. Copy circle 22 2 times, one to the lower intersection of circles 33 and 36, the other one to the corresponding intersection of this copied circle itself. Retain only the last one.

38. Copy circles 12, 14, 16, 18, 20, 22, 23, 25, 28, 30, 32, 35 and 37, and rotate them together 180° around the center of middle circle 1. Together with the original ones, and circles 1, 2, 3, 4, 5, 6 and 8, they form the basis for the reconstruction.

39. Remove all parts not visible in the formation.
