The Story Behind 'Be Thou My Vision'

The story behind Be Thou My Vision reaches back more than a thousand years to an Old Irish poem, "Rop tú mo baile," and forward to two women in the early twentieth century who gave it to the English-speaking church. Few hymns we sing today are so old, and few came to us by such a long road.

An ancient Irish prayer

The original is an Old Irish poem traditionally dated to around the eighth century and sometimes attributed to the poet Dallán Forgaill. It belongs to a stream of early Irish Christianity that prayed in vivid, personal images — God as a shield, a stronghold, a high tower, a father, a beloved. To pray "be thou my vision" was to ask God to be the very way one saw the world.

For centuries the poem lived in the Irish tongue, copied and recited but unknown to most of the wider church.

Two translators

In 1905, an Irish scholar named Mary Elizabeth Byrne translated the poem into English prose. Her rendering was faithful but not yet singable. Seven years later, in 1912, Eleanor Hull — a writer and student of Irish literature — took Byrne's prose and shaped it into the metrical verses we now know: "Be Thou my Vision, O Lord of my heart."

It is worth pausing on that. The hymn is not the work of a famous preacher or a celebrated composer. It reached us through the patient, largely unnoticed labour of two women translating an old language into a form the church could sing.

The tune called Slane

The words are wedded to "Slane," a traditional Irish folk melody. The tune takes its name from the Hill of Slane in County Meath, where — according to a well-loved legend — Saint Patrick lit a paschal fire in open defiance of the high king's command, announcing that a greater King had come. Whether or not the legend is exact, the pairing is fitting: an ancient Irish prayer set to an ancient Irish tune.

What the words ask

The hymn is a series of requests, each asking God to occupy a place we usually reserve for something else. Be my vision — my very sight. Be my wisdom. Be my "best thought, by day or by night." Then it turns to the things people chase: "Riches I heed not, nor man's empty praise, Thou mine inheritance, now and always." The closing verse looks past everything else to God as the only lasting treasure: "High King of heaven, my victory won, may I reach heaven's joys, O bright heaven's Sun."

Why the story matters

We live surrounded by things asking to be our vision — our screens, our ambitions, the good opinion of others. A prayer written more than a thousand years ago names them all as "empty praise" and asks for something steadier. That an eighth-century Irish Christian and a twentieth-century Irish scholar and the modern family in the pew can pray the very same words is a quiet argument for the unity of the faith across the ages.
