Reconstruction of the
Yarnbury Castle 24-06-2018 formation

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

2. Construct the inscribed hexagon (regular 6-sided polygon) of circle 1, pointing up.

3. Construct the inscribed hexagon of circle 1, pointing to the right.

4. Construct a circle centered at the uppermost righthand intersection of hexagons 2 and 3, tangent to circle 1 at the near side.

5. Construct a circle concentric to circle 1, tangent to circle 4 at the lower side.

6. Construct the inscribed hexagon of circle 5, pointing up.

7. Draw six rays of circle 1, to the angular points of hexagon 2.

8. Construct a circle concentric to circle 1, passing through the intersections of hexagons 2 and 3.

9. Construct a "two-points" circle (defined by the two end-points of a centerline) between the intersections of the upper righthand ray 7 with hexagon 3 and circle 8. See detail.

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

11. Construct a line, parallel to the upper righthand ray 7, tangent to circles 9 and 10 at the upper lefthand sides.

12. Construct a circle inside hexagon 6, tangent to its upper sides, and tangent to line 11.

13. Repeat step 12 (and all necessary previous steps) five times, with respect to the other angular points of hexagon 6, as shown.

14. Construct a circle centered at the lefthand intersection of the two righthand circles 13, tangent to circle 12 at the near side. See detail.

15. Copy circle 14 six times, to the angular points of hexagon 2.

16. Copy circle 9 six times, to the centers of circles 15.

17. Construct 3 pairs of parallel lines, parallel to rays 7, tangent to circles 16 at both sides.

18. Circles 12, 13, and 15, hexagon 6, and lines 17, are used for the final reconstruction.

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