A chronicle from Stasbourg, written in 1604 and widely seen as the first account of a Christmas tree in German-speaking lands, records that Protestant artisans brought fir trees into their homes in the holiday season and decorated them with "roses made of colored paper, apples, wafers, tinsel, sweetmeats, etc." ... The Christmas tree spread out in German society from the top down, so to speak. It moved from elite households to broader social strata, from urban to rural areas, from the Protestant north to the Catholic south, and from Prussia to other German states.
The eight-pointed star became a popular manufactured Christmas ornament around the 1840s and many people place a star on the top of their Christmas tree to represent the Star of Bethlehem.
