Halloween, like many modern American holidays, is a kind of mashup of different cultural traditional traditions rooted in the autumnal harvest, and some kind of celebration or connection with the spirit world. You see it in Mexico with Dia de los Muertos; and in pre-Christian Ireland, it was Oíche Shamhna ("Shamna" being the genitive form of "Samhain," which is pronounced kind of like "SOW-un," and actually just means "November").
An episode of The Irish Passport podcast takes a close look at the roots of those Gaelic traditions, and the kind of generation loss that happened when it was exported to the United States, and then re-imported back to Ireland. The result is kind of fun-house-mirror reflection of itself—modern Irish imitating a mutated American imitation of older Irish traditions. You'll also get to learn a bit about how the faeryfolk in Ireland, the Aos Sídhe, still play an active role in modern real estate development in the Republic (yes really).
Just below the surface of modern Ireland, a parallel world exists with its roots in pre-Christian belief. Irish fairies aren't like Tinkerbell—they're more like a supernatural mafia. So be careful what you say, because as the story goes, they're probably listening. Tim talks to one of Ireland's last seanchaí or story-teller historians, who once managed to get a highway diverted to prevent the felling of a fairy bush. We also hear about modern traditions from the streets of Galway as the Celtic New Year Samhain festival is underway.
