All but one of Le Moyne's original drawings were reportedly destroyed in the Spanish attack on Fort Caroline; most the images attributed to him are actually engravings created by the Belgian printer and publisher Theodor de Bry, which are based on recreations Le Moyne produced from memory.
The images of the Timucua and related maps, said to be based on Le Moyne's drawings by de Bry, have fallen under intense scrutiny and their legitimacy as works related to Le Moyne are considered very questionable.
