I’m not going to pretend that I’ve ever heard of Wilhelm Leibl, but I thought this painting had a bit of depth to it. He is apparently one of the most important German realist painters and he lived from 1844 until 1900, with this artwork being painted in around 1878 to 1882. The aim of the artist was to portray three different generations in a state of prayer and contemplation.
I have no knowledge of this other than having read it on-line, but this is also the most important work which was painted by Leibl. The Kunsthalle obtained the painting in 1906 and it’s apparently a forerunner of the ‘neue sachlichkeit’ generation, or the ‘new objectivity’ movement.
