Perinaldo, Land of Astronomers
The astronomer Giovanni Domenico Cassini opens his autobiography with these lines in French that specify his exact birthdate. Cassini on this occasion wants to emphasize and correct the error reported by the Abbot Michele Giustiniani in his work, Ligurian writers, a book collecting various information about the most important representatives in the fields of Letter and Sciences from Liguria, the region in the Northwest of Italy, where he was born. The attention to such details shown by Cassini should not surprise the reader. Scientific accuracy and rigor always characterized his astronomical work, and sometimes was at the core of conflicts or misunderstandings, even, for example, with the King of France, Louis XIV.
