Origin of Christmas trees came from pre-Christian traditions. At the solstice, the ancient Egyptians filled their homes with green palm rushes, which symbolized the triumph of life over death in honor of the sun god Ra. Ancient Romans marked the solstice with a celebration called Saturnalia in honor of Saturn, the god of agriculture. They decorated their homes and temples with evergreen boughs. The mysterious druids, priests of the ancient Celts, decorated their temples with evergreen boughs as a symbol of everlasting life. The Viking believed evergreen boughs were the special plant of the sun god, Balder. Germany is credited with starting the Christmas tree tradition as we now know it in the 16th century.
Merry Christmas and Happy Yule!
