‘Gaelic erotica’ was published as a lengthy article in Kryptádia, vol. 10 (1907), pp. 295–367. The piece is structured as a little encyclopaedia, with 103 entries in Gaelic and English, ranging from ‘Aed, fire’ to ‘Water. Wells.’ The terms are illustrated with various usages culled from songs and anecdotes.
As might be expected, the article is entirely anonymous, both regarding writer and informants. To those versed in Scottish Gaelic folklore, however, certain clues in the foreword, and the nature and scope of the material discussed, point to one candidate only. The writer has been ‘[e]ducated as a medical jurist’ ; all his material ‘has been collected by persons of education … all being Scottish Highlanders using Gaelic from their childhood upwards’ [295–6]. These hints suggest that the writer of ‘Gaelic erotica’ was none other than the very respectable scion of an Edinburgh medical dynasty, Robert Craig Maclagan (1839–1919).
