One of the greatest lyrical poets in Spanish of any age, St John of the Cross (1542-1591) enjoys an authoritative status as a theologian and teacher of the mystical road to union with God. St John of the Cross covers all his works, both poetry and prose, citing the original Spanish and providing English translations throughout. Its focus is firmly on the language through which he seeks to express the inexpressible and the theological insights he brings to the mystical way.
