Samhain is one of the festivals that mark the wheel of the year. It’s the third harvest festival when gourds and root vegetables were harvested.
As a cross-quarter festival it is a thin time when the boundary between our world and the other world is easily crossed.
You might be visited by your relatives who passed so you would light their way with lanterns made with gourds and turnips. You’d set a place at the table for them as well.
All of this devil bullshit is the church demonizing Celtic traditions.
You bet. Samhain is midway between Mabon (equinox) and Yule (solstice) so it was widely observed among Celtic and Germanic peoples.
