First and foremost I offer thanks to Professor Jürgen Richter-Gebert. I learnt the story this essay endeavours to tell from his excellent book Perspectives on Projective Geometry (Richter-Gebert 2011), in particular Chapters 1 and 15.

I would also like to thank Professor Fran Burstall who both taught me projective geometry and introduced me to Richter-Gebert’s work.
