The first printed edition of it was issued at Augsburg, in 1558, by Achilles Gasser. In 1562, Jean Taisner published from the press of Johann Birkmann of Cologne a work entitled Opusculum perpetua memoria dignissimum, de natura magnetis et ejus effectibus, Item de motu continuo. This is considered a piece of plagiarism, as Taisnier presents, as though his own, the Epistola de magnete of Peregrinus and a treatise on the fall of bodies by Gianbattista Benedetti.
