Giovanni Domenico Cassini I taught astronomy in Bologna. He was the director (1671) of the Royal Observatory in Paris. His brilliance and reputation rests upon many scientific achievements: the ‘Cassini ovals’, the first measurement of the size of France, and the discovery of the big red spot on Jupiter, an observation he shared with Robert Hooke.
