Some recent studies of the Heptaplomeres have tended to cast some doubt on Bodin’s authorship of this work. Even if the issue of his authorship has not been decisively resolved, one of the secondary but beneficial consequences of these studies is that they have increased our understanding of the on sources which the author of this anonymous text drew — including not only the Daemonomania as well as the other works by Bodin, but also the writings of Johan Wier (1515–1588; Wier 1579).  The most important studies questioninig Bodin’s authorship of the treatise are those by Karl F. Faltenbacher (2002, 2009) and David Wootton (2002), Jean Céard (2009) and Isabelle Pantin (2009). Refutations of this thesis, on the other hand, have been published by Jean Letrouit (1995), Andrea Suggi (2005, 2006, 2007) and Noel Malcom (2006).
