Récréations mathématiques et physiques by Jacques Ozanam, 1723
The fourth volume of the 1723 edition of Jacques Ozanam's 'Récréations mathématiques et physiques' (which was first published in 1694 by Jombert in Paris but revised and expanded from two to four volumes after his death in 1718) contains a rather out-of-place final section, titled 'De Gibeciere', explaining how to perform magical tricks. It is believed that responsibility for the revised edition, and thus for the section on magic, rests with Martin Grandin, who was a professor of philosophy at the University of Navarre.
