The Origin of the Tradition of Bringing Christmas Trees Indoors

Leave a comment

During the Ancient Roman Saturnalia festival near the winter solstice, coniferous branches, boughs, and trees were brought indoors and kept. Although the exact rationale is debated, the concept may have developed as a means to symbolize everlasting life and/or as a method to ensure the god Saturn, the patron deity of time, wealth, and agriculture among other things within Ancient Rome, would prolong summer and shorten winter. In the 4th century A.D. this festival was replaced by the Christian holiday of Christmas which adopted the practice of bringing trees indoors as well. It should be noted, bringing coniferous trees indoors during the winter solstice was a pagan tradition throughout the northern hemisphere, with multiple cultures and empires outside of the Ancient Romans adopting the practice

Moss does not only grow on the north side of trees, as it is commonly believed by many. Moss typically grows on the north side but this rule only applies in the northern hemisphere. In the southern hemisphere, moss mostly grows on the south side of trees. The reason for this inversion is that in the northern hemisphere, because of the tilt of the Earth on its axis, the sun almost always appears to be a little south of directly overhead. That’s why rooms with windows facing south are brighter than rooms with windows facing north. This is important for moss because the north sides of trees within the northern hemisphere are shadier and therefore wetter. The south sides of trees get more sunlight, so water evaporates faster there
