This ornamented list of Celtic paranormal creatures is one explanation of why North Americans see us the way they do. Tourists from the US often expect to trip over a leprechaun every day here, whilst running from the Dullahan and hearing the Banshee outside the whitewashed stone cottage with the thatched roof (no doubt after having consumed way too much poitín). The Irish tourist board might need to adjust the imagery a tad.
The Sluagh mentioned in this list could be mistaken for Irish capitalists. Is Micheal O’Leary one of them?
