William Grant Stewart, The popular superstitions and festive amusements of the Highlanders of Scotland (1851)
“ Attired in a shroud and all the ensigns of the grave, the ghost nocturnally proceeds to the narrow house of his future residence, and there disappears. He is lighted on his way by a pale azure-coloured light, of the size of that emitted by a tallow candle, which is of a flickering unsteady nature, sometimes vivid, and sometimes faint, as the mortal inhales and respires his breath; and, in his course towards the grave, he will follow minutely the line of march destined to be followed by his earthly partner’s approaching funeral. ”
