Circle Limit 3, executed in 1959, depicts an infinite number of fish again. It is a very refined and re-worked version of Circle Limit 1. In Circle Limit 3, the fish look more like fish. Also if you trace the arcs present in the print you see the fish beginning as infinitely small fish and then growing in size as we move towards the center of the print and then diminish in size as we move to the outer radius of the print. Artistically, it is a much more satisfying approach to infinity.
Circle limit 4, executed in 1960, depicts an infinite number of angels and devils. The duality of infinite good and infinite evil. Escher titles this print Heaven and Hell. A print he executed as he approached a serious operation. Look at it as angels in the foreground and devils in the background. In this way they are understood as infinities ever separated into Heaven in the foreground and Hell in the background. In this late print Escher returns to the concept of Heaven and Hell. But he depicts the infinite sense of these two realms in an artistically satisfying way by incorporating the sense of infinity into the print
In part 7 we summarize Escher’s mandalas.
