Roy Jenkins looks at the life, work and continuing influence of Isaac Watts, the great hymn-writer who was born in Southampton 350 years ago.

Of the six or seven hundred hymns he composed a good handful are sung each week in services across the denominations, and some have become fixed points in worship for Easter, Christmas and even Remembrance Sunday. Ironically, some have made their way into Anglican hymnaries, despite the fact that Watts and his family faced severe privations for not worshipping at an Anglican church - his father was imprisoned on several occasions for being a 'dissenter'. Certain hymns (notably 'Joy to the World') have been translated into many languages, including Cherokee, German, French, Zulu Welsh. Celebrated in his day as a profound thinker, poet and logician Watts' influence is felt far and wide for introducing the practice of making emotionally expressive hymns an integral part of worship.
