Arthur Edward Henderson

Arthur Edward Henderson carried a Winsor & Newton tin of watercolors in his coat pocket for decades, sketching cathedrals between trains. He never trained in Spain but spent summers in Galicia copying the Portico de la Gloria’s tangled stone figures until his pencil matched the original’s rhythm. Why keep at it? He wrote on the back of one sheet: “The echo of every chisel is still in the air.” Hunt down his 1922 watercolor in the same cathedral—it’s pinned inside the south transept, tucked above a side door where tourists rarely look.
