specifically blame it on his marriage:
It is very interesting to examine what happens to his painting when, later on in his life, he marries and settles down. The inner turmoil and dark beauty of his earlier work give way to a period of "normality" exemplified in his later paintings in the somehow bland and frankly considerably less interesting depiction of trees from parks in Brussels. He has turned the page, switched on the light and moved away from the dangerous tightrope balancing act over the abysss to the tree trunk stability of a family life routine. Art can only be fueled by what is real. For Spilliaert, the choice of a normal family life brought calm, satisfaction and fullfilment as a person but as an artist the price to be paid was indeed very high.Tormented creator of immortal art, or contented normality? Hard choices. But if this is right, Spillaert got to experience both, and that seems like a good life to me.
