Jack imprisoned Death in a nut, but the world was at a standstill until Death was released.
Jack made himself ill eating unripe gooseberries. Death came to him in a dream on his sickbed. Jack said he wasn't ready for death. Jack and Death fought and Jack won. He put Death in a nut and flung it into the sea. Nothing died after that. Animals couldn't be butchered for meat, corn wouldn't ripen, and the world was at a standstill. Jack's mother sent him to her sister who was a henwife living by the sea. The henwife told him to wander the shores until he found the nut. He found it after a year and a day. He offered to let Death out if he promised not to come for him for 100 years. This was agreed, Death got out, and everything went back to normal.
