XI/3 As in the case of Homer in Canto IV one of the tiny heads from the initial image of Canto III is enlarged (almost X50) to represent the face of Aristotle. It is set upon a graph and contains a grid deriving from that graph in which the Aristotelian systematisation of morals which Virgil urges Dante to recall is mapped by variously shaded values. These in their turn degenerate in the lower region of the brain into more and more shapeless areas of illogicality. -- Source of annotation: Marvin or Ruth Sackner.
