Decorating a tree with lights and ornaments has become a common tradition, and we almost forgot that its origin has nothing to do with the Christian world and came instead from a pagan celebration. In fact, many centuries ago, the Germanic people already used a pine tree every year to celebrate the winter solstice on December 21. According to Germanic mythology, the evergreen pine tree was the symbol of vital energy and reminded men that, even during winter, nature was not dead and was about to start a new life cycle.
