… Diet Sayler does indeed follow self-prescribed rules of construction which determine the composition of each work. However, his compositions are certainly not predetermined by systematic calculation. … His rules of composition bear the stamp both of mathematical considerations and a random generator (for instance the throwing of dice). Thus thinking and feeling, objectivity and subjectivity are perfectly counterbalanced in Sayler's work. …
It is also the combination of both aspects—rational clarity and emotional aura—to a compositional whole, and perhaps exactly this, that defines the particular significance of Diet Sayler’s oeuvre.
