Martin's painting

It is only a forest.
In the first place I met this painting in a book, thus it was fair to place a book in the painting. It owes its title to a protagonist of this novel, though the latter is only an alibi.
For the first time there is no character in it. However, the painting is far from being anonymous. In front of the blank canvas, it's difficult to know were exactly we're aiming at. We need to write the pages, we have to work our way.
We can learn a lot about ourselves by painting a forest.
