The custom of decorating trees is older than Christmas itself. Already before Christ virtually all pagan cultures and religions wore ornaments on trees to celebrate the fertility of nature.
The Romans adorned the trees in honor of Saturn, who was their God of agriculture.
In Egypt it was customary, at the winter solstice, to bring green branches into their houses, as a way of celebrating life's victory over death.
The Celtic druids, in festive times, decorated the oaks with golden apples.
The earliest records of the adoption of the Christmas tree by Christianity emerge from northern Europe in the early sixteenth century, although everything indicates that by that time it was already a tradition coming from medieval times, as there are records of "Christmas Trees" in Lithuania around Of the year 1510.
In the old Christian calendar, December 24th was dedicated to Adam and Eve and its history used to be staged in the churches. As a representation of paradise was used a tree laden with fruits.
The Christians then gained the habit of mounting this allegory in their houses with trees that, over time, became more and more decorated: the stars symbolizing the Star of Bethlehem, candles symbolizing the light of Christ and the roses in honor To the Virgin Mary.
During the seventeenth and eighteenth centuries this habit became so popular among the Germanic peoples that they attributed the creation of the Christmas tree to its congenial Martinus Luter, founder of Protestantism. Pray the Germanic legend that Luther wandered during a clear night through the forest, observed the effect of the stars on the top of the trees and brought that image to his family in the form of a tree with a star on top and decorated with candles.
