174. O Gladsome Light

The Story Behind the Hymn

This hymn's underlying Greek text, known as 'Phos Hilaron' ('gladsome light'), is one of the oldest Christian hymns outside the Bible still in regular use today, with a documented history of congregational use reaching back at least to the third century and quite possibly earlier, making its likely original author entirely unknown and its exact date of composition impossible to pin down with precision.

The hymn was traditionally sung each evening at the lighting of lamps, a specific liturgical moment in ancient and early Christian worship marking the transition from daylight to evening, and the text's central image of Christ as a 'gladsome light' shining even as the physical daylight fades carries direct, literal meaning within that original evening lamp-lighting context, rather than functioning only as an abstract poetic metaphor.

The fourth-century Christian bishop and theologian Basil the Great, writing in the 370s, already referred to this hymn in his own writing as an old and traditional song whose original composer was, even by his own considerably earlier era, no longer known or remembered, meaning the hymn was already considered ancient by the standards of the fourth-century church, roughly seventeen centuries before its use in this present collection.

Robert Bridges, an English physician who later abandoned medicine for poetry and eventually served as Britain's Poet Laureate from 1913 until his death, translated the ancient Greek text into the English version most commonly used today, part of his broader work compiling and translating hymns for English congregational use during his own literary career, bringing a text already many centuries old into English-language worship only in comparatively recent history.
