Thomson on the back-translated Gaelic-language product of 1807:

It seems safe to conclude that the 1807 Gaelic version of this story is not a piece of genuine Gaelic composition in the sense that the [Gaelic] ballads are. Indeed it shows the strong influence of Macpherson's English of 1762, and it must be concluded that it was translated from that English...
That it was composed by somebody who was extremely careless of Gaelic syntax is certain.
