“All Hallows Eve” is a stand-alone chapter about a Welsh Halloween from Traits and Stories of the Welsh Peasantry (1849) — a wonderfully detailed and lovingly written novel with an extremely misleading title. (The frame story is that these are people the English author knows personally, and that this is a folklore book; but it seems pretty clear that she did make the story up, although both story and characters are very plausible.) We don’t hear much about the Welsh side of Celtic customs in this country, so I think you’ll enjoy it. Another great forgotten book from Stanford’s library and books.google.com!
This chapter is all about old Pally Lewis’ annual All Hallows’ Eve festivities, and goes into details of the Welsh customs of the day. It also sounds like a really fun way to spend Halloween!
