A delightful video.
Queen Mary was visiting the Funen Village near the city of Odense, which is an open air museum with farms and homesteads from 16-1700s. Absolutely worth a visit for a history buff. There is a similar museum in Aarhus, The Old Town, which is an affluent merchant town from 1600-1850. Now also with a section from the the 1970s - I feel old!
Anyway, Queen Mary and the curator of the museum talked about Christmas traditions on Christmas Eve, they have actually been covered in the Christmas thread a few years back. (They well be mentioned in parenthesis here.)
People slept in alcoves, but not on Christmas Night! On Christmas Night the dead returned and that also included dead relatives. And being a kind of guests they were to sleep in the alcoves. I guess it would kind of creepy to share your bed with a ghost...
Charity was very much a part of Christmas, there you earned some brownie points with God by also feeding the poor. (They went from door to door during Christmas BTW.)
The food was left out on the table throughout all the twelve days of Christmas. There the food soaked up the Christmas spirit/blessing and the leftovers were ploughed into the fields come spring, ensuring a good harvest.
Animals were also fed well during Christmas. - (But you never ever went into the stables on Christmas Night! On that night the animals could speak and they did. But if anyone was foolish enough to go out and try and listen to the animals, they would become mute. So no one ever learned what the animals said. That superstition existed well into the 1900s in some more remote parts of DK.)
The Nisse (a kind of house-spirit that has probably existed since farming began in DK some 6.000 years ago) was also treated on Christmas Night. A bowl of porridge was placed in the attic in order to placate the Nisse. If the Nisse was pleased some of the porridge had been eaten (cats, mice and rats no doubt).
(The Nisse is not to be confused with an elf. A Nisse was first a house-spirit that took on a more physical form during the 1600s, which is the reason why he, it was always a man, was dressed a peasant attire. He looked after the farm and it's inhabitants, humans and animals. Sometimes causing mischief, but if offended he could be really mean! Causing illness, misfortune even death among humans and animals. And if you moved away from the farm, the Nisse went along. Hence a common saying in DK: The Nisse moves along. = The problems/issues you have, will follow you if not dealt with.
Later on the Nisse was married and became an old benign figure, and eventually he evolved into a helper of Santa and not too bright!) The Nisse got his name, because a very common name back then was Niels, and short for Niels was Nis (it's Niller today), hence Nisse.
The Nisse would look pretty much like this around 1700:

QM and the curator addressed each other with formal You, even though the curator at one point used informal you. Not that I think Queen Mary would mind one bit. - But I personally prefer that the senior DRF members at least are addressed with formal You. It's part of the show I think, as well as showing respect for the office.
