“At the museum” does not show the expected: people looking at art or at any other content of interest. It just suggests – vaguely – an empty museum bench.
The function of the museum is reduced to what many people experience in the museum: fatigue.
The empty museum can be interpreted as an expression of a nihilistic vision: it suggests that the most interesting object to put your eyes on in a museum is… the empty bench in the middle of the room.
The title is ironic and suggests only one of various possible interpretations: the painting can for instance also be interpreted as an abstract one, just showing a rectangular shape, or gust as an expression of a certain state of being fed up with the number of images we have to process daily.
