Matthys' oeuvre, in which images are central under all their forms and expressions, is firmly rooted in a long process in which each phase adds a new layer. The many works, the many images, are each separately part of a larger whole in which the distance between them is often negligible.
Then again, some works stand alone; after all, the images themselves determine when they are finished. There, the attentive viewer senses that it is finished and forms a chapter or paragraph in itself. It transcends and dominates the long working process that preceded it.
