Never before translated into English, these two massive volumes narrate the exciting story of the amazing spiritual transformation that affected Wales between the years 1735 and 1850. Of great value is the use the authors make of eye-witness accounts preserved in contemporary diaries, journals and letters. A truly exhilarating read! These stimulating and enjoyable volumes narrate the exciting story of how Wales was spiritually transformed and the men whom God used to accomplish that great work. 'The Lord gave the word: great was the company of those that published it' (Psa. 68:11). In this first volume, which focuses on the revivals experienced in South Wales, we meet the well-known figures of Daniel Rowland, Howell Harris, William Williams of Pantycelyn; but within these wonderful pages are portraits of many lesser-known preachers such as Griffith Jones of Llanddowror, Howell Davies, Peter Williams, and David Jones of Llan-gan.
