Some more French Christmas folklore...
After the western corner of the country, let's move a bit to the East...
When you check books such as "Fêtes de Noël et du Nouvel An autour du monde" (Sophie Lounguine) or "Dictionnaire des fées et du peuple invisible dans l'occident païen" (at Brepols) you get mentions that, in eastern regions of France, winter witches are roaming by Christmas time...
In the Haute-SaĂ´ne, these witches (unless they are but one witch - as with the "bogeyman/bogeymen" the exact singularity of these entities is unclear) are called "Trotte-Vieille". The Trotte-Vieille seems to have originally been an ogress, described as a horned hag who devoured children unless you left for her a pot of porridge by the threshold of the house. However through time they became more of a "Mother Christmas" figure, now bringing gifts to nice children... While nasty chldren were thrown by her (or them) into the nearby river as a punishment.
The Trotte-Vieille is considered to be of the same family, if not the same entity as the Chauche-Vieille (or les chauche-vieilles) and the chauche-pailles (or la Chauche-Paille) (punish those Christmas mass) whom, in areas like Doubs or Jura, act as "Mother Christmas" figures bringing gifts, but also as Christmas "bogeywomen", notably devouring those that did not go to the Christmas mass. In French-speaking Switzerland, the Chauche-Vieille was explicitely identified with the German Frau Holle.
What is very interesting with "chauche-vieille", however, is that she has a full on existence outside of her Christmas duty. In a reversal of the Père Fouettard figure (originally a Christmas-only figure that became a bogeyman by default), the name "chauche-vieille" was originally a generic folklore term to designate... a nightmare. In the folkloric sense, the supernatural entity-nightmare. A nightmare is a "cauchemar" in France, and "chauche-vieille" is an oral deformation of it - alternatively called Chausse-Vieille, Chouche-Vieille, Chauco-Vieillo), she is the French "night hag" by excellence, present in areas like Bresse, Forez or Savoie as an ugly and wicked old woman who sits on the stomach of sleepers to smother them. It was deemed, in typical Christianization fashion, that she attacked those that forgot to pray before going to sleep or read "pagan books" - in turn the chauche-vieille could be banished by prayers or a rosary... But older traditions remain, such as the superstition according to which the chauche-vieille was only banished if you spill a bowl of grain at her arrival, forcing her to count every grain (just like vampires and certain types of ghosts - in fact the "mare", "mara" of nightmare has been interprete as meaning not just "witch" but also "ghost" or "spirit").
And she became associated with Christmas, seemingly, because it became commonly told the chauchevieille would come smother you if you did not go to the Christmas mass - as a punishment for those sleeping instead of celebrating... In the vaudois area of Switzerland, for example, she exists as the gift-giver of Christmas (whereas "Le Bon Enfant", "The Good Child", a variation of the Christkindl, acted as the gift-giver of New Year). As Tsousevilhe or Tschautzevilha she offered children food - originally nuts, but today oranges, chocolates and candies. It also seems, with time, that she was associated in language with the figure of "Père Chalande" (the New Years gift-giver/Father New Year figure), down to being considered by some the "wife" or "female companion" of Père Chalande.
And all of these frightening-yet-sweet witches of winter, all frequenting Germanic-influences areas of France, or French areas of Germanic countries, culminate within one specific figure. One of the most famous regional gift-givers of France. Tante Arie (Aunt Arie). Considered both a witch and a fairy, present in areas like Doubs, Jura or Franche-Comté (but her tradition most active by Montbéliard), it is commonly agreed that she is another incarnation or avatar of the Germanic figure that gave birth to Frau Holle/Holda and Frau Perchta (for, just like Perchta, she is sometimes said to have iron teeth ; just like Holda, she is said to cause snowfall by ripping her white shirt ; and like both of them she seems to have been connected to the motif of the Wld Hunt during winter storms).
Tante Arie is depicted as a gift-giver coming to town either on Christmas night or during the Epiphany. Riding a donkey (sometimes named Marion, revealed it is a female donkey), she usually goes in the house either down by the chimney or through a window left open for her (though variations mention her slipping under the door). To nice kids, she leaves sweets in their shoes - and they can hear the bell of her donkey (for whom hay must be left). To naughty children, however, she leaves birch branches so they parent could beat or whip them. And to disobedient or lazy kids, she leaves dunce caps.
Tante Arie also acts as a "household fairy", who blesses the houses she visits and likes (helping children go to sleep, helping work be done in the field - in general, anybody encountering good luck or a fortuitous good event thought it was the doing of Tante Arie). Just like the divine Germanic figures, she also was connected to weaving and spinning - when she discovers hard-working spinsters and weavers (especially if they are poor girls, or shepherdesses) she helps them and bless their work ; but if she discovers lazy girls, she will mix their threads and damage their work in an unrepairable way. Her connection to threads also makes her a figure connected to fishermen, that she can torment by making knots in their lines or unhooking every fish they catch. (She also seemingly checks the quality of the bread of bread-makers?)
A Montbéliard legend claims that Tante Arie is just the mythification of an historical figure, the comtess Henriette d'Orbe-Montfaucon, who was so kind to the people of the 15th century that the Doubs inhabitants turned her into a benevolent spirit watching over their life, into a good fairy. ("Arie" would be a diminutive of "Henriette"). However, as we said, she clearly seems much more "mythical" than this... Especially given that she is sometimes said to have goose feet instead of human feet, which connects her to the Pédauques fairies and queens that populate the culture and legends of France since the Middle-Ages...
