3. |
Construct the inscribed hexagon (regular six-sided polygon) of circle 2, pointing to the left. | |

4. |
Construct the inscribed hexagon of circle 2, pointing up. | |

5. |
Construct a circle (concentric to circle 2), passing through the intersections of hexagons 3 and 4. | |

6. |
Construct the inscribed circle of hexagons 3 and 4. | |

7. |
Construct the inscribed hexagon of circle 6, pointing to the left. | |

8. |
Construct the inscribed circle of hexagon 7. | |

9. |
Construct the inscribed equilateral triangle of circle 8, pointing up. | |

10. |
Construct the inscribed circle of triangle 9. | |

11. |
Copy circle 10 to the center of circle 1. | |

12. |
Construct two inscribed hexagons of circle 5, one pointing to the left, one pointing up. | |

13. |
Construct a circle (concentric to circle 2), passing through the intersections of hexagons 12. | |

14. |
Construct the circumscribed hexagon of circle 5, pointing to the right. | |

15. |
Copy circle 10 to the righthand angular point of hexagon 14. | |

16. |
Construct the inscribed hexagon of circle 1, pointing to the right. | |

17. |
Copy circles 5, 6, 8, and 13, five times, to the other angular points of hexagon 16, as shown. | |

18. |
Construct a circle concentric to circle 1, passing through the center of circle 15. | |

19. |
Construct the inscribed hexagon of circle 18, pointing to the right. | |

20. |
Copy circle 10 five times, to the other angular points of hexagon 19, as shown. | |

21. |
Construct the "two-points" circle (defined by the two end-points of a centerline) between the righthand intersections of circles 5 and 6 with the horizontal centerline. | |

22. |
Construct a circle concentric to circle 1, passing through the center of circle 21. See detail. | |

23. |
Construct the inscribed hexagon of circle 22, pointing to the right. See detail. | |

24. |
Copy circle 21 five times, to the other angular points of hexagon 23, as shown. See detail. | |

25. |
Construct three pairs of parallel lines, tangent to opposite circles 21 and 24, at both sides, as shown. See detail. | |

26. |
Circles 5, 6, 8, 11, 13, 15, 17, and 20, and lines 25, are used for the final reconstruction. | |

27. |
Remove all parts not visible within the formation itself. | |

28. |
Colour all areas corresponding to standing... | |

29. |
...or to flattened crop, and finish the reconstruction of the 2017 Fonthill Down formation. | |

30. |
The final result, matched with the aerial image. |
