"Be Thou My Vision" (Old Irish: Rop tú mo baile or Rob tú mo bhoile) is a traditional hymn from Ireland. The most well known English version, with some minor variations, was translated by Eleanor Hull and published in 1912. In 1919, the lyrics were set to the tune of the Irish folk tune "Slane", to which the song is sung to this day, both in English and Irish. The song dates from at least the eighth century, though it has often been attributed to the sixth-century Irish Christian poet Saint Dallan.
