The evolution of plastic Christmas trees

It is said that plastic Christmas trees first appeared on the Saturn Festival in ancient Rome in mid-December. The German missionary Nigus used a fir tree to worship the Holy Child in the 8th century. Subsequently, the Germans took December 24th as the festival of Adam and Eve. They put a "paradise tree" symbolizing the Garden of Eden at home, and hung cookies representing holy bread to symbolize atonement; candles and balls were also lit to symbolize Christ. In the 16th century, the religious reformer Martin Luther designed a plastic Christmas tree filled with candles and balls in order to obtain a starry Christmas night.
