Modern art has lost all of its greats this year.
For me there are 2 stages to the experience of a great inspirational artist passing. At first there is the profound sadness that there will never be any new work from them again, and then in turn that emotion changes into a real sense of having lost the person. The greatest artists, in any field, express their vision so coherently, we end up feeling that we know them - that is the mark of greatness.
A sad year.
