The relief assumes three dimensions and evokes depth. Depth, in its broadest sense, is the innermost and the most difficult part to penetrate. It is infused with mystery. I think that the artist must tend to escape the tyranny of the visible and, by his/her expression should suggest, reveal the depth and trigger the imagination of every one. The value of a painting is measured by the extent of its imaginary halo, it allows the experience of openness, the experience of novelty, of freedom. Just as the value of life does not lie in its surface but in its depths, the things seen are not made up of their bark only, but also of their core. Paintings, like men, are not in their visible appearance but in their essence.
