| 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. |
