What we know as Rembrandts most famous painting, The Night Watch, is actually just not the whole thing. Only seventy-three years after it was finished, the painting was trimmed in order for it to fit into its new location, the Amsterdam town hall. About 60 centimeters were removed from the left side, and smaller strips from the other three sides. Because of that, the composition is now unbalanced, and some of the figures have been removed – just like that.
Also, the popular name is based on a misunderstanding. The Night Watch (whose original title is The Company of Frans Banning Cocq and Willem van Ruytenburch is not set at night at all! The misleading title was given to the painting in the 18th century, since the varnish had grown so dark over the years. The scene was thus misinterpreted as being nocturnal.
It isn't the smartest thing to marry a prince that is nicknamed "the Fair" when you have a tendency to jealousy, one would say. But princesses in the 15th century couldn't choose their husbands; their marriages were arranged for political reasons. Joan was one of the luckier girls, since she was betrothed to a man she absolutely adored: Philip of Austria. He lived up to his nickname, and on the night the two first met, it was love - or lust - at first sight. Philip insisted they would marry immediately so the young couple could love each other passionately.
Unfortunately, their attraction would turn out to be fairly unequal: Philip's feelings for Joan were mere desire, whereas Joan loved her husband obsessively. But he was young, handsome and on top of that he was a monarch (he ruled the Low Countries from the age of 18), so women lay to his feet and he loved it. He acted as if he was a young bachelor, drinking, feasting and having sex excessively. Joan was extremely jealous; she wanted her husband for her and herself only.
She often was moody and depressed, or could also break out in jealous rages. Philip couldn't care much, he would rather make things worse by avoiding her bedroom after they had been fighting over one of his excesses. She would cry of anger and despair and bump to the wall ceaselessly. Instead of starting to hate him, however, her mad love for him remained. He was all that she cared for: she lost all interest in politics and became isolated at court.
