I remember a story, a short novel I think, it was written in the last century but in it's core I think it has some relation to folklore.
It's narrated from the viewpoint of a child in a poor rural family during their hard times. He tells about an evening when his grandpa went into the "smelly". It's basically his suicide by going into a cave with sulfuric gases. He dress up in his nice suit, has a ritualistic last supper and leaves. The whole thing has a very tense and depressing atmosphere.
Supposedly this type of suicide, to kill the least useful members of the family during hardships wasn't known on the Hungary but it was/is among steppe people. Also Eskimos.
