Ascent of Mount Carmel and Dark Night of the Soul by Saint John of the Cross.

The sixteenth century Carmelite monk Juan de Yepes (canonized in 1726 as Saint John of the Cross) drew upon the long tradition of apophatic mysticism to chart the ascent of Mount Carmel, which is his image for the ascent of the soul to God. There is reason to believe that Saint John was familiar not only with the writings of the early apophatic mystic, Pseudo-Dionysius the Areopagite, but also such later ones as Eckhart and Ruysbroeck. Saint John, however, provides a precise, comprehensive, and elegant description of the way of unknowing that is missing in preceding texts.
