Reconstruction of the 2017 The Rollright Stones formation | ||

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

2. |
Construct the inscribed octagon (regular 8-sided polygon) of circle 1, pointing up. | |

3. |
Draw the eight diagonals of octagon 2, from each angular point to every third angular point, as shown. | |

4. |
Construct the inscribed square of circle 1, with horizontal and vertical sides. | |

5. |
Draw the eight diagonals of the octagon enclosed by diagonals 3, from each angular point to every third angular point, as shown. | |

6. |
Construct the inscribed circle of (the octagon enclosed by) diagonals 5. | |

7. |
Copy circle 6 to the top of octagon 2. | |

8. |
Construct a circle concentric to circle 1, tangent to circle 7 at the upper side. | |

9. |
Construct the inscribed square of the circumscribed circle of the octagon enclosed by diagonals 3, with horizontal and vertical sides. | |

10. |
Construct a circle centered at the mid-point of the righthand side of square 9, tangent to circle 6 at the righthand side. | |

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

12. |
Construct the inscribed circle of the octagon enclosed by diagonals 3. | |

13. |
Copy circle 12 to the lower intersection of circle 7 and the vertical centerline. | |

14. |
Construct a circle concentric to circle 1, tangent to circle 13 at the upper side. | |

15. |
Construct a circle centered at the mid-point of the upper side of square 9, passing through the upper intersections of diagonals 5, as shown. | |

16. |
Copy circle 15 to the upper intersection of circle 8 and the vertical centerline. | |

17. |
Construct a circle concentric to circle 1, tangent to circle 16 at the lower side. | |

18. |
Circles 6, 8, 11, 14, and 17, diagonals 3, and square 4, together, make up the final reconstruction. | |

19. |
Colour all areas corresponding to standing... | |

20. |
...or to flattened crop, and finish the reconstruction of the 2017 The Rollright Stones formation. | |

21. |
The final result, matched with the aerial image. |
