Folding fan with two paper leaves on which the question-and-answer game 'l'Oracle' is printed and colored, on a carved ivory mount fitted with 'métal en quatre couleurs'. 15 non-connected openwork ribs. The paper leaves are printed and painted. On the front, a wheel of fortune and two putti holding the inscription 'l'Oracle', centrally with fortune-telling tables on either side, including questions in a cartouche. On the back, ten columns with god names and their attributes. With the question-and-answer game 'Oracle', the future could be predicted. Two numbers were required for this: first, one had to choose the number of the question. The second number was obtained by blindly poking with an ivory arrow, which hung from the fan with a string (missing here), into the wheel of fortune in the middle of the fan. The second number referred to the lists of gods on the left and right of the wheel, while the first number was used to find the required god in the corresponding list.
