From the beginning in 1967 until 2002, Sol LeWitt’s artist books are collected in this volume. In his works the systematic rationalism, in its extreme consequences, is translated in a sort of immaterial mysticism.Accompanied by the artist’s words, Sol LeWitt’s works in form of books create with his exhibitions relations of planning and poetic affinity, rather than formal. In other words, the book is not a mere copy of the painting, but a mirror and a different point of view from where observing the same idea.
