Olentzero https://plomin.club/santa-klaus/"Наведемо певні додаткові подробиці щодо «Діда Мороза» чи «Святого Миколая». У Країні Басків «Дід Мороз» має ім’я Оленцеро. Ось вам свідоцтво церковної ворожнечі до цього образу: 23 грудня 1952 року діда Мороза висотою близько трьох метрів повісили з величезною пишністю на воротах собору Нансі."
Дело тут, кажется, все же не в "церковной враждебности".
"Other variations of the legend, customs and the character include:
• in Areso children would be told to come home early. An adult would then dress up as Olentzero and scare the children still out on the streets with a sickle.
• in Uharte-Arakil he was traditionally suspended from a rope from a window, dressed in a straw mantle, in Lekunberri the effigy was attached to the chimney.
• in Berastegi if the children did not want to go to bed, a sickle would be thrown down the chimney and the children told that Olentzero would come to cut their throats if they did not go to bed.
• in Dima a straw puppet dressed as Olentzero with a sickle would be hung from the church tower after the midnight mass on Christmas Eve and if children had been behaving badly, people would say
Onontzaro begi-gorri txaminira da etorri, austen baldin badegu barua, orrek lepoa kendu guri ("Olentzero with the red eyes has come to the chimney, if we break the fast, he will cut our throats") - referring to the traditional fast in the week before Christmas."
