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 has often been attributed to the sixth-century Irish Christian poet Saint Dallan, though some scholars cite an eighth-century date.'. Question: 'who wrote the song be thou my vision'.
