ABSTRACT
After the initial interest expressed by the author of the Pro Insipiente, little attention appears to have been paid to the Proslogion. Even within the writings of Anselm’s immediate circle, there is a surprising lack of interest. Although Gilbert Crispin uses a variant of the formula ‘X’,1 he does not do so in the context of a discussion of Anselm’s argument. Even a follower such as Rodolfus Monachus, who, like Anselm, is concerned to address the unbeliever, fails to advert to the argument of the Proslogion, presenting instead an argument for the existence of God as first cause in his Libellus de Nesciente et Sciente.2
