J. C. Ryle described Daniel Rowland (1711–1790) as ‘one of the spiritual giants of the eighteenth century.’ Lady Huntingdon considered him to be ‘second only to Whitefield.’ Howel Harris wrote of him, ‘In his pulpit he is second to St Paul,’ while others acclaimed him as ‘the greatest preacher in Europe.’ Yet he has been one of the least known leaders of that age.
The loss of manuscripts shortly after his death, the Welsh language barrier, and the fact that all his closest friends were also preachers rather than authors, all contributed to leave only a shadowy impression of his greatness. However, after many years of work, Dr Eifion Evans succeeded in breaking through a multitude of difficulties to present for the first time a full-scale biography of Daniel Rowland.
