Reconstruction of the
2018 Martinsell Hill 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 down.
|
|
3. |
| Draw the five diagonals of pentagon 2.
|
|
4. |
| Draw the five diagonals of the pentagon enclosed by diagonals 3, and extend these lines upto pentagon 2 in both directions. Number the intersections with pentagon 2 clockwise 1 - 10, starting at the top left.
|
|
5. |
| Draw the five diagonals of the pentagon enclosed by diagonals 4, and extend these lines upto pentagon 2 in both directions. Number the intersections with pentagon 2 clockwise 11 - 20, starting at the top left.
|
|
6. |
| Draw five connecting lines between the following pairs of numbered intersections: 11 and 18, 12 and 15, 13 and 20, 14 and 17, and 16 and 19.
|
|
7. |
| Draw five connecting lines between the following pairs of numbered intersections: 1 and 8, 2 and 5, 3 and 10, 4 and 7, and 6 and 9.
|
|
8. |
| Draw five connecting lines between the following pairs of numbered intersections: 1 and 4, 2 and 9, 3 and 6, 5 and 8, and 7 and 10.
|
|
9. |
| Complete the ten small, peripheral pentagrams (regular 5-pointed stars) by drawing every three respective connecting lines, as shown. See detail.
|
|
|
|
10. |
| Complete the five small pentagrams, in between pentagrams 9, by drawing every two respective connecting lines, as shown. See detail.
|
|
|
|
11. |
| Construct the circumscribed circle of the pentagon enclosed by lines 5. See detail.
|
|
|
|
12. |
| Copy circle 11 to the upper intersection of circle 1 and the vertical centerline.
|
|
13. |
| Construct a circle concentric to circle 1, tangent to circle 12 at the upper side.
|
|
14. |
| Circle 13, and lines 3, 4, 5, 6, 7, 8, 9, and 10, are used for the final reconstruction.
|
|
15. |
| Remove all parts not visible within the formation itself.
|
|
16. |
| Colour all areas corresponding to standing...
|
|
17. |
| ...or to flattened crop, and finish the reconstruction of the 2018 Martinsell Hill formation.
|
|
18. |
| The final result, matched with the aerial image.
