Turner's Revolutionary Method

Turner's late paintings were so radical that critics called them unfinished. He would exhibit nearly blank canvases at the Royal Academy and then work on them during Varnishing Day — the preview period when artists could apply final touches — adding entire compositions while rival painters watched in astonishment.

This performance aspect anticipated modern art practices by over a century. Turner treated painting as a live event, blurring the line between creation and exhibition. His willingness to rework canvases publicly challenged the myth that great art emerges fully formed.
