"It is revealing that Heckel was drawn to the Baltic Sea. You have to see this vast body of water with your own eyes to understand that it is can reflect light like a gigantic mirror, with an intensity that is not limited to the coastal strip, but also touches nearby stretches of land in a way that you can tell the distance to the sea from the high and clear air - it is no coincidence that Heckel would name one of his paintings after this phenomenon."
