A Bit of Dark, A Bit of Light, A Bit of Space
By the end of this book, we know many things about the professional and personal life of Cassini and his family. He dealt with an impressive list of astronomical and also non-astronomical problems, collecting many successes and rewards, and leaving an important heritage to future generations. But this is not the whole story yet, and among his activities there are “shadows” among the lights, as well as some curious aspects that are worth mentioning. In this last chapter, therefore, we want to list some of these less known facts: “défaillances”, failures, the design of particular objects, and his last project connected to the city of Bologna.
