John Ruskin (1819-1900) was a man who could do anything (and did): he was an art critic, he wrote essays and poetry, and he painted watercolours.
It is this last thing that interests me most.
Ruskin painted landscapes and portraits, but I love his nature studies best.
It can be almost meditative to look at something this close, and try to capture it.
Ruskin was an absolute master in it.
