The Cloud of Unknowing draws on radically different traditions to evoke an abstract, transcendent God, beyond human understanding. A new translation by A.C. Spearing, this also includes three other works by the same author, thought to be a priest and Carthusian monk: The Mystical Theology of Saint Denis, The Book of Privy Counseling and An Epistle on Prayer. Appendix reproduces the Middle English text of part of The Mystical Theology of Saint Denis.
