As we see the inversion of perspectives in Dalí’s Le jeu lugubre we can also ‘experience’ the ‘normal’ POV. (i.e what we see) The very idea of changing perspectives is what we find in the notion of anamorphosis. It engages the variety of alterations of the visible,or to put it simply, it is an altered viewpoint. The famous example of this is Hans Holbein’s Ambassadors. In the middle of the painting there is a seemingly unidentifiable ‘patch’, which only grants recognition by being viewed at an anamorphistic POV.
If viewed from the appropriate angle we can see a skull.
Only with the help of various perspectives can we integrate our notion of reality, but the question is, which perspective is real?
