Here is an interesting video about Yule. It’s all about the the light.
The winter solstice (solstice is Latin for “sun standing still”) happens at the same time for everyone on Earth. It represents the exact moment when the Northern Hemisphere is tilted at its furthest point away from the sun.
Winter solstice is an astronomical phenomenon marking the shortest day and the longest night of the year.
Worldwide, interpretation of the event has varied across cultures, but many have held a recognition of rebirth, involving holidays, festivals, gatherings, rituals or other celebrations around that time.
The pagan Scandinavian and Germanic people of northern Europe celebrated a twelve-day “midwinter” (winter solstice) holiday called Yule
Many modern Christmas traditions, such as the Christmas tree, the Christmas wreath, the Yule log, and others, are direct descendants of Yule customs.
Sol Invictus (“The Unconquered Sun”) was originally a Syrian god who was later adopted as the chief god of the Roman Empire under Emperor Aurelian. His holiday is traditionally celebrated on December 25, as are several gods associated with the winter solstice in many pagan traditions.
