This beautiful hymn is No. 36 in the Oxford Hymn Book (1908). The Dorian Melody is out of the same stable as Tallis's "Third Mode Melody," used by Ralph Vaughan Williams in his Variations on a Theme of Thomas Tallis and it is surprising that it is not more widely known. John Mason (d. 1694) was educated at Clare Hall, Cambridge and was later Rector of Water Stratford in Buckinghamshire. His collection of religious poems, Songs of Praise, was published in 1683.
