Shule/Shool AroonA. P. Graves reworked "Shule Aroon" and Dr. Douglas Hyde translated that into Gaelic about 1890. That's the only fully Gaelic version, so isn't 'ancient'. Four earlier versions, two Scots, and 2 Irish, are given in the Scarce Songs 2 file on my website. It's debatable whether the Gaelic chorus was originally Scots or Irish. The song was probalby known in the late 18th century, but there's no evidence for it that early.
