Reconstruction of the
St Martin's Chapel 3-07-2010 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 pentagram (regular 5-pointed star) of circle 1, by drawing the diagonals of pentagon 2.

4. Construct the inscribed pentagram of the pentagon enclosed by pentagram 3, by drawing its diagonals.

5. Construct a circle concentric to circle 1, passing through the mutual inner intersections of diagonals 4.

6. Construct the inscribed pentagon of circle 1, pointing down.

7. Extend the upper righthand side of pentagon 2 and the lower righthand side of pentagon 6 to the right, until they intersect (at the horizontal centerline).

8. Repeat step 7 for all other corresponding pairs of sides of pentagons 2 and 6, as shown.

9. Construct a circle concentric to circle 1, passing through the intersection of lines 7.

10. Construct the inscribed decagon (regular 10-sided polygon) of circle 9, pointing to the right.

11. Extend the upper lefthand and righthand sides of decagon 10, until they intersect (at the vertical centerline).

12. Repeat step 11 for all other corresponding pairs of sides of decagon 10, as shown.

13. Extend the upper lefthand and righthand sides of pentagram 3 up to lines 11.

14. Extend the other corresponding pairs of sides of pentagram 3, up to lines 12.

15. Construct the inscribed pentagram of circle 1, by drawing the diagonals of pentagon 6.

16. Repeat steps 13 and 14 for all corresponding pairs of sides of pentagram 15.

17. Construct the circumscribed pentagon of circle 9, pointing up.

18. Construct the circumscribed pentagon of circle 9, pointing down.

19. Construct the inscribed pentagram of circle 5, pointing up.

20. Construct a circle concentric to circle 1, passing through the mutual inner intersections of the sides of pentagram 19.

21. Copy circle 20 ten times, to the intersections of pentagons 17 and 18.

22. Construct the inscribed circle of pentagram 19.

23. Copy circle 22 ten times, to the angular points of pentagons 17 and 18.

24. Draw two lines, one between the intersection of the upper side of decagon 10 with the righthand line 13 and the intersection of the lefthand line 11 with the lefthand line 13, the other between corresponding points mirrored with respect to the vertical centerline. Extend both lines upto pentagon 17, as shown.

25. Repeat step 24 nine times, for all other corresponding sides of decagon 10, lines 14 and 16 and pentagons 17 and 18, as shown.

26. Copy circle 22 twenty times, to the end-points of (extended) lines 24 and 25, as shown.

27. Construct a circle centered at the upper intersection of circle 22 and the vertical centerline, tangent to circle 20 at the upper side.

28. Copy circle 27 twenty times, to the centers of circles 26.

29. Pentagram 3, circles 5, 21, 23, 26 and 28, and lines 7, 8, 11, 12, 13, 14 and 16, are used for the final reconstruction.

30. Remove all parts not present within the formation itself.
