A post on Samhainn will follow shortly, but in the meantime I just wanted to bring a beautiful short film to your attention.
I can't embed the video here, it seems, but follow this link to watch it - it's only eight minutes long and the visuals are quite beautiful. The film references a few traditional stories about An Cailleach Bheara, although it concentrates on one in particular; I found this ages ago and meant to post it, but lost the link and it's only now I've found it - in good time for the season, perhaps!
Anyway, if you haven't seen it already, enjoy.
