Isaac Watts was an English Congregational minister, hymn writer, theologian, and logician. He was a prolific and popular hymn writer and is credited with some 750 hymns. His works include "When I Survey the Wondrous Cross", "Joy to the World", and "Our God, Our Help in Ages Past". He is recognised as the "Godfather of English Hymnody"; many of his hymns remain in use today and have been translated into numerous languages.

A hymn is a type of song, and partially synonymous with devotional song, specifically written for the purpose of adoration or prayer, and typically addressed to a deity or deities, or to a prominent figure or personification. The word hymn derives from Greek ὕμνος (hymnos), which means "a song of praise". A writer of hymns is known as a hymnist. The singing or composition of hymns is called hymnody. Collections of hymns are known as hymnals or hymn books. Hymns may or may not include instrumental accompaniment. Polyhymnia is the Greco/Roman goddess of hymns.
