Abstract
Since its origin, Greek philosophy has made an attempt to rationally determine what the 'divine', object of myth and religious practice, really is. In the present article we examine Proclus's project of a philosophical theology. First, by determining its object (theion) : the absolute One and the henads, secondly by distinguishing its method (logos) from other forms of theological discourse : symbolic-mythological, eikonic and oracular. Finally, we explain how Proclus came to understand the logical discussion in the Parmenides of Plato as the perfect system of scientific dialectical theology, a philosophical 'hymn of the generation of the gods'
