Mirella Bentivoglio comments that the works of Di Sarro (1941-1979), who was a doctor, should be considered as precursors to art as writing, a tendency which developed in Rome in the sixties in the work of Emilio Villa, Marco Balzarro, and Luciano Cattania. She adds that this was followed by the well known Roman tendency of sign-abstraction, "impersonated" by Capagrossi, Novelli, and Twombly. -- Source of annotation: Marvin or Ruth Sackner.
