About Cu Sith

The Green Hound of the Sithein

Scottish Gaelic tradition knows a large green fairy dog, the cù-sìth, whose barks (often three) are a death omen. Collectors (J. G. Campbell, later folklore archives) place it on the moors between this world and the sìth mounds. It is not Cú Chulainn's hound.

The record is oral and early-modern; there is no medieval tract devoted to the beast.

Three barks

In the Highland lore gathered by John Gregorson Campbell in Superstitions of the Highlands and Islands of Scotland (1900), the fairy dog moves silently and leaves footprints as large as a man's hand. It barks three times, with long pauses between, and anyone who has not reached safety by the third bark is overtaken by terror or death. Women were sometimes said to be taken by it to nurse fairy children in the mounds.
