Reconstruction of the 2017 Battlesbury Hill formation | ||

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

2. |
Construct the inscribed square of circle 1, with the sides parallel to the horizontal and vertical centerlines. | |

3. |
Construct the inscribed circle of square 2. | |

4. |
Construct the inscribed square of circle 3, pointing to the right. | |

5. |
Construct the inscribed circle of square 4. | |

6. |
Construct a circle centered at the upper righthand angular point of square 2, tangent to circle 5 at the upper righthand side. | |

7. |
Copy circle 6 three times, to the other angular points of square 2. | |

8. |
Construct a circle concentric to circle 1, passing through the lower intersection of square 2 and circle 6. | |

9. |
Construct a circle concentric to circle 6, tangent to circle 8 at the upper righthand side. | |

10. |
Copy circle 9 three times, to the centers of circles 7. | |

11. |
Construct the circumscribed square of circle 8, with the sides horizontally and vertically. | |

12. |
Construct a "two-points" circle (defined by the two end-points of a centerline) between the upper righthand angular points of squares 2 and 11. See detail. | |

13. |
Repeat step 12 three times, with respect to the other angular points of squares 2 and 11. | |

14. |
Construct two pairs of parallel lines, parallel to the diagonals of square 11, tangent to circles 12 and 13 at both sides. See detail. | |

15. |
Construct a circle centered at the righthand intersection of circle 1 and the horizontal centerline, passing through the upper lefthand intersection of square 11 and circle 12. See detail. | |

16. |
Copy circle 15 to the center of circle 1. | |

17. |
Construct a circle centered at the lefthand intersection of circles 6 and 8, tangent to circle 16 at the near side. | |

18. |
Construct a circle concentric to circle 6, tangent to circle 17 at the lefthand side. | |

19. |
Copy circle 18 three times, to the centers of circles 7. | |

20. |
Draw the connecting line between the centers of circles 1 and 6. | |

21. |
Construct a "two-points" circle between the intersections of circles 5 and 9 with line 20. | |

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

23. |
Construct a circle concentric to circle 6, passing through the center of circle 21. | |

24. |
Copy circle 17 to the lower righthand intersection of circles 21 and 22. | |

25. |
Copy circle 17 to the upper lefthand intersection of circles 21 and 23. | |

26. |
Copy circles 24 and 25 three times, by repeating steps (20, 21, 23,) 24, and 25, with respect to circles 7 in stead of circle 6, as shown. | |

27. |
Circles 1, 5, 6, 7, 8, 9, 10, 16, 18, 19, 24, 25, and 26, and lines 14, are used for the final reconstruction. | |

28. |
Remove all parts not visible within the formation itself. | |

29. |
Colour all areas corresponding to standing... | |

30. |
...or to flattened crop, and finish the reconstruction of the 2017 Battlesbury Hill formation. | |

31. |
The final result, matched with the aerial image. |
