Reconstruction of the
Oliver's Castle 15-04-2007 formation

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

2. Construct the inscribed pentagon (regular 5-sided polygon) of circle 1, pointing up.

3. Construct the inscribed circle of pentagon 2.

4. Construct a "two-points" circle (defined by the two end-points of a centerline) with the points at the lefthand intersections of circles 1 and 3 with the horizontal centerline.

5. Copy circle 4 to the lefthand intersection of circle 3 and the horizontal centerline and move this circle (copy and delete original) to its own righthand intersection with the horizontal centerline, as shown.

6. Construct a circle centered at the intersection of the lower side of pentagon 2 and the vertical centerline, passing through the lower righthand angular point of this pentagon.

7. Copy circle 6 to the center of circle 1.

8. Construct a two-points circle through the lefthand intersection of circle 7 and the righthand intersection of circle 5, both with the horizontal centerline. See detail.

9. Copy circle 8 to the center of circle 1.

10. Copy circle 4 to the lefthand intersection of circle 9 and the horizontal centerline and move it to its own corresponding intersection. See detail.

11. Copy circle 4 to the lefthand intersection of circle 10 and the horizontal centerline and move it to its own corresponding intersection.

12. Copy circle 8 to the lefthand intersection of circle 11 and the horizontal centerline.

13. Copy circle 4 to the center of circle 1 and move it to its righthand intersection with the horizontal centerline.

14. Copy circle 4 to the righthand intersection of circle 13 and the horizontal centerline and move it to its own corresponding intersection.

15. Copy circle 1 to the lefthand intersection of circle 8, and move it to its own righthand intersection, both with the horizontal centerline. See detail.

16. Copy circle 1 to the lefthand intersection of circle 12, and move it to its own righthand intersection, both with the horizontal centerline. See detail.

17. Copy circle 1 to the lefthand intersection of circle 10, and move it to its own righthand intersection, both with the horizontal centerline.

18. Copy circle 1 to the lefthand intersection of circle 9, and move it to its own righthand intersection, both with the horizontal centerline. See detail.

19. Copy circle 1 to the righthand intersection of circle 13, and move it to its own righthand intersection, both with the horizontal centerline.

20. Copy circle 1 to the righthand intersection of circle 14, and move it to its own righthand intersection, both with the horizontal centerline.

21. Copy circle 1 to the righthand intersection of circle 7, and move it to its own righthand intersection, both with the horizontal centerline.

22. Construct a circle concentric to circle 15, tangent to circle 7 at the lefthand side.

23. Copy circle 22 six times, to the centers of circles 16, 17, 18, 19, 20 and 21.

24. Circles 1, 3, 15, 16, 17, 18, 19, 20, 21, 22 and 23 together make up all that is necessary for the final reconstruction.

25. Remove all parts not visible in the formation itself.
