Administrative historyGiussepe Campani observed Saturn as a central globe surrounded by a ring, which he published as 'Ragguaglio di due nuove osservazioni' [Summary of two new observations] (1664). Adrian Auzout agreed that there was a shadow on the lower part, but objected to the continuous dark band on the interior edge of the ring at the top of the of figure. Auzout expressed his objections in his Lettre à M. l’Abbé Charles (1665). Campani had in fact observed what is now known as the crêpe ring of Saturn (see Albert Van Helden, 'Annulo Cingitur: The Solution of the Problem of Saturn', Journal of the History of Astronomy, 5 (1974), 155-74 (pp. 167-68)).
