The purpose of this note is to discuss a few lines appearing in the work of late Fantappiè. They concern the proof of rigidity of a specific real semisimple Lie algebra: \mathfrak O(4,1). Our intention is to discuss to what extent such proof constitutes a missed opportunity in history of post-war Italian mathematics.
