The ancient Egyptians, Hebrews, and Chinese used evergreen trees and wreaths as symbols of eternal life. In the Middle Ages, the Christmas tree was first used in Germany and originally decorated with candles and wafers. In the same room, during the Christmas season, was the Christmas pyramid, a triangular construction of wood, with shelves to hold Christmas figurines, decorated with evergreens, candles, and a star. By the 16th century, the Christmas pyramid and tree had merged, becoming the Christmas tree. In the 19th century, the Christmas tree was used throughout Europe and the United States.
