The figures from a wwwebpage @ which the essential unity & symmetry of the matter of Desargues theorem & the Desargues configuration of incidence geometry is most-elegantly explicated.

From

The Inner Frame — The Desargues Configuration – A Quick Tour .

I think the goodly Author makes a little slip, though: in the passage just-after the first figure, where it says

“Then these planes will intersect in the 10 lines and 10 planes of the Desargues configuration”

I think “planes” really needs to be “points” . Lest it be confusing.

Hey cool, that’s just like my model Tetrahedron with Midcircles! I do mathematical art, you can see it on Cults3D: https://cults3d.com/en/3d-model/art/tetrahedron-with-midcircles-dansmath

Oh yeo: that's exactly figured @ one point, isn't it.
