Peter Randall-Page is next up. He very kindly allowed us to display some of his artwork on the stage this year.
He is speaking on theme and variation, commonly associated with music, but he is applying it to nature. It is ubiquitous but hardly noticed.
At 6, the Natural History Museum sent him a box of fossils. He was dyslexic, so learnt through means other than words. He found lots of patterns. Patterns in nature are generally created through opposing processes, and there is a limited book of patterns, which could be understood as driving the evolutionary process itself. Without an organising principle, what would randomness look like?
He is showing some wonderful images on screen. The latest are the Giant’s Causeway and a hornets nest. Both have hexagonal packing. Neither are perfect because geometry only exists in human imaginations. And yet we intuitively understand this. We enjoy the dangerous unpredictability of variation, and the common underlying theme.
Variation is not a singularity. In art it implies playfulness and expression. So Peter work often uses sequences in his work – e.g. images of walnut kernels – to build up expressions of qualities through comparison. As an aside, we seem to respond to bilateral symmetry, probably because our bodies are symmetrical.
The shape of pine cones and pineapples is to do with efficient packing, relating to the Fibonacci Sequence and the Golden Ratio, and is very pleasing to the eye. Peter used this principle in his work ‘Seed’ for the Eden Project.
The underlying principles of the microscopic pattern generated by two chemicals that don’t mix reminded Peter of playful improvisational music. The phenomenon produces the camouflage patterns on zebra and mackerel. The resulting artwork – a combination of painted canvas and boulders – Peter called Rocks in my Bed, after the song by Duke Ellington.
Variation also implies an element of chance. So Peter often uses the random, e.g. a weathered boulder, and a structuring principle, e.g. an overlaid geometric net. Compare with fish-net tights, which help us to see and appreciate the form of the leg more clearly!
Fundamentally, Peter is interested in what makes us tick, and subconsciously tries to bring it out. He shows a piece using a random boulder and a continuous line – ref Paul Klee ‘taking a line for a walk’. Another is based on the Platonic solids, sculptured from a chaotic material.
Back to spirals, and an image of a galaxy, illustrating the different scales of theme and variation. We need both: theme without variation is monotonous; variation without theme is chaotic. Together they can create beauty in nature, music and art.
