The tradition of Christmas trees and Christmas Ornaments is a much disputed one what with several theories about their origin doing the rounds for a long time. The most popular theory holds that the tradition was started by a monk who came to Germany in the 7th/8th century to preach. It is said that this monk was Saint Boniface, the Apostle of the Germans. According to history, the saint was the first one to bring a fir tree to the German people to decorate, for he believed that its triangular shape represented the Holy Trinity - God, his son Jesus, and the Holy Spirit. The tradition was lapped up by the devout Germans who started decorating the Christmas tree in a liturgical way with simple, white candles. This however, changed in the 15th century when ornaments began to be incorporated into the Christmas decorations in Germany. In Latvia, circa 1510, a fir tree was decorated with roses which were associated with the Virgin Mary. This event is often hailed as the pioneer of modern Christmas decorations.
