The metaphysical poet Henry Vaughan is much anthologized – “I saw Eternity the other night”, “They are all gone into the world of light’; but it is not so well known that he was a native of the Usk valley, and that it is the light on the river and hills of Brecknockshire that shines through his poetry. Inspired by George Herbert, his work interweaves the natural and the spiritual world. Three Vaughan scholars celebrate his work and sense of place.
