Some painters thought hard about the golden section and others came to the same result by instinct. Here are two paintings by very different Welsh artists from the 1930s.
Vincent Evans was a painter who planned his paintings carefully with techniques of composition. After the Blast shows miners repairing an underground roadway in a coalmine after an explosion. The artist created a symmetrical shape of timbers and a strong line across the middle. He then used the golden section to position the two miners. The clarity of the composition helps you imagine the skill and care of the miners.
Vertical features on the golden section are: on the right the face and knee of the kneeling miner and the foot of the standing miner, and on the left the head of the standing miner. Horizontal features on the golden section are: the top the belt of the kneeling miner and the hat of the standing miner, and on the bottom the hands of the standing miner.
