Reconstruction of the
West Overton 17-08-2007 formation

1. This formation consists of a pattern of identical tiles in the central part. The reconstruction follows three main steps. First, one tile will be reconstructed, then, the tiling pattern will be laid out, and finally, the border part will be reconstructed.


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

2. Copy circle 1 to its righthand intersection with the horizontal centerline. Move this circle (copy and delete original) to its own corresponding intersection.

3. Create a "Vesica Pisces", by constructing two circles, concentric to circles 1 and 2, each passing through the center of the other circle, as shown.

4. Copy circle 1 to the upper intersection of circles 3.

5. Copy circle 1, while mirroring with respect to the (line between the) centers of circles 2 and 4.

6. Create a diamond, by drawing four "point-to-point" lines, from the center of circle 1 to the centers of circles 2, 5, 4 and back to 1, in that order.

7. Copy diamond 6, while mirroring with respect to its lefthand side.

8. Copy diamond 6, while mirroring with respect to its lower side.

9. Construct two circles, centered at the upper angular point of diamond 7 and at the lower righthand angular point of diamond 8, each passing through the mid-points of both nearest sides of diamond 6, as shown.

10. Draw four lines, two each from the lower lefthand and from the upper righthand angular points of diamond 6, to the mid-points of both opposite sides, as shown.

11. Create one tile of the central tiling pattern, by removing all redundant parts.

12. Copy tile 11, while mirroring with respect to its upper side.

13. Copy tile 12, while mirroring with respect to its righthand side.

14. Copy tile 13, while mirroring with respect to its upper righthand side.

15. Copy tile 13, while mirroring with respect to its lower righthand side.

16. Copy tile 15, while mirroring with respect to its lower side.

17. Copy tile 15, while mirroring with respect to its righthand side.

18. Copy tiles 11 through 17 as a whole five times, while rotating each over (a multiple of) 60°, dividing evenly around the lefthand angular point of tile 11 (the center of circle 1), as shown.

Together with the copied tiles, this forms the central tiling pattern.

19. Extend the upper righthand side of tile 17 downwards, and its mirrored counterpart with respect to the horizontal centerline upwards, up to their mutual intersection, as shown.

20. Draw a horizontal line from the righthand angular point of tile 17 to the right.

21. Extend the lower line 19 up to line 20.

22. Repeat step 19 for the upper righthand corner of the tiling pattern (rotated 60°), as shown.

23. Draw a line from the upper righthand angular point of tile 14, upwards and to the right, angled at 60° with respect to the horizontal centerline.

24. Extend the upper line 22 to the right, up to line 23.

25. Draw the connecting line between the intersections of lines 20 and 21, and lines 23 and 24.

26. Copy circle 9 (one of both) to the lower angular point of tile 17.

27. Draw a horizontal line from the center of circle 26 to the right.

28. Construct a "two-points" circle, defined by the end-points of a centerline, one of which coincides with the mutual intersection of lines 19, the other with the intersection of circle 26 and line 27.

29. Draw two lines, parallel to line 21, one from the center of circle 28, the other from its righthand intersection with line 27, both up to line 20.

30. Draw two lines, parallel to line 25, from both intersections of lines 29 and line 20, up to line 23.

31. Draw a line, parallel to line 23, from the upper lefthand angular point of tile 14, upwards.

32. Draw two horizontal lines, from both intersections of lines 30 and line 23, to the left up to line 31.

33. Copy lines 21, 24, 25, 29, 30 and 32 as a whole five times, while rotating each over (a multiple of) 60°, dividing evenly around the lefthand angular point of tile 11 (the center of circle 1), as shown.

34. Draw two lines, from the intersection of lines 21 and 25, and of the lefthand lines 29 and 30, to their mirrored counterparts with respect to the horizontal centerline, as shown.

35. Construct a "two-points" circle, the points of which coincide with the intersections of lines 34 and the horizontal centerline.

36. Copy circle 35 five times, to the other corresponding positions around the border pattern, as shown.

37. The final reconstruction makes use of tiles 11, 12, 13, 14, 15, 16, 17 and 18, lines 21, 24, 25, 29, 30, 32 and 33, and circles 35 and 36.
