It’s one of my absolute favorite paintings of all time.  Take a look at that lighting as it dances across the floor and over the backs of the floor workers.    The strong diagonals of the floor and the paneling of the walls create this mesmerizing composition.  It’s almost too perfect.  I read somewhere that photography greatly influenced Caillebotte’s work.  I can see that now.  His work is wonderful.
