In the example, many tubes are drawn in a pile. In this messy still life, only one tube is completely visible! Of all the other tubes, you only see a part because of the overlaps.
Exercise: think of things/materials that you can stack or throw in a pile in a fantasy drawing.
In 1961, the Belgian artist René Magritte painted a whole pile of buildings on a large lawn. It is a strange painting, because in real life we do not encounter mountains of houses piled on top of each other. And do we still call this a still life? Isn’t it more like a landscape? Aren’t still lifes usually objects on a table? Magritte liked to paint things that you only encounter in a dream or fantasy world.
