The Log Cake story.. which is real..?

The Christmas Day party at my aunt's place was great.. Everyone had lots of fun, we eat, we drink, we joke... and be merry... Many guests brought wines of different types.. there are Bordeaux, Merlot, Shiraz, Cabernet Souvignon and Ice Wine... During dinner time it was like a wine tasting session, we open up the wines bottle by bottle and taste it one by one.. The alcohol content in the wine bring up the atmosphere...

Then after dinner came the log cake... And my dad and my aunt starts to talk about the origin of log cake.... Why was only Christmas then we are able to eat log cake? Why there is no log cake for birthdays and other occasions..? Everyone gave a different version of the log cake origins.. Here are some of the stories...

My dad says during winter time, many people are cold so some of the farmers start to burn logs to keep them warm.. and since in modern days we no longer burn logs to keep us warm.. thus the origin of log cake to represent the "Yule Log"..

My aunt gave another version of hers.. saying because baby Jesus was born in a horse stable, thus they burn logs to keep baby Jesus warm...

One of the guest gave another interesting version... Because baby Jesus was born in a stable and only have a blanket to cover, thus the log was lay in a cross position to act as a cradle for baby Jesus...

So what is the really origin of the Christmas log cake and who's version was correct.. I did a check in the Internet.. and here is the results from the Wikipedia:

A Yule log is a large wooden log which is burned in the hearth as a part of traditional Yule or Christmas celebrations in several European cultures. It can be a part of the Winter Solstice festival or the Twelve Days of Christmas, Christmas Eve, Christmas Day, or Twelfth Night.
The expression "Yule log" has also come to refer to log-shaped Christmas cakes, also known as "chocolate logs" or "Bûche de Noël". The Yule log is related to other Christmas and Yuletide traditions such as the Ashen faggot.

The British Version: Herrick called the tradition a "Christmas log" and said that it was brought into the farmhouse by a group of males, who were then rewarded with free beer from the farmer's wife. Herrick claimed that the fire used to burn the log was always started with a remnant from the log that had been burned in the previous year's festivities. He also said that the log's role was primarily one of bringing prosperity and protection from evil - by keeping the remnant of the log all the year long the protection was said to remain across the year.
In traditional British rural culture, the Yule log was not only seen as a magical protective amulet, and there are many reports of rivalries occurring between members of a community as to who had the largest log.

The Europe version: The Yule log has frequently been associated with having its origins in the historical Germanic paganism which was practiced across northern Europe prior to Christianisation.

There are so many stories about Christmas log cake.. but my dad version is the closest to the British version... And for me i just loves to eat Log Cake...

Merry Christmas and a Happy New Year!!!
