What are the Sources of Pseudo-Dionysius' "Spiral of Love?"

This paper traces the sources of Pseudo-Dionysius’ “Spiral of Love” (Divine Names IV, 10) to a single Neoplatonic origin. It demonstrates that all four modes of Erôs between the different beings, namely the reversive, the communal, the providential, and the conservative, go back to Proclus himself, who has explicitly coined and conceptualized all four of them in different contexts of his extant works. Nevertheless, Pseudo-Dionysius adapted this Proclean quadripartition to his own Christian and creationist system.
