Eight Chapters on Perfection is Hilton’s translation of a Latin text by the Aragonese Friar Dom Lluis de Font, and is the only surviving record of that manuscript. It is a text of great humanity and wisdom about the possibilities of friendship and love between those drawn to prayer. In Angels’ Song Hilton’s own spirituality is revealed as he considers how, in the spiritual life, the action of grace can be distinguished from pious illusion.
