Asbjorn Lonvig's words: What I was really enthusiastic about in Notre-Dame de Paris was one of the 3 large rosettes - a mosaic made out of stained glass. The sun was shining the morning I visited Notre-Dame de Paris and the light was bursting through the colorfull stained glass. Amazing. The Swiss psychologist C. G. Jung would probably have called these rosettes mandalas - and sure they are. Wikipedia's words: Notre-Dame de Paris has a significant treasure: its 3 large rosettes. These examples of technical and artistic skills were constructed in the 13th century. The largest 2 measure 13 metres in diameter. The King Saint Louis posponed his departure for the 2nd crusade so he could see them completed. It was in 1270, and he never came back. They represent the flowers of Heaven, which resemble roses with multi-coloured glass in stained glass technique. Each coloured petal sets off the others, but the design is not only used for its visual impact, it is a reminder that everyone is unique, but the children of God are even more beautiful when they come together! Each medallion represents a different person, Prophets, Saints, Angels, Kings, Scenes from the lives of the Saints, work through song, virtues… all whirling on vast wheels around the central medallion, which features two rose windows depicting the Virgin and Baby Jesus and another showing Christ in majesty. The South Rose Window was a gift from the king Saint Louis. It was designed by Jean de Chelles and Pierre de Montreuil. The first stone of the south transept façade was laid in 1258. The South Rose Window, a central element that thrones over the transept façade, was constructed in 1260 as a counterpoint to the North Rose Window, which was built in 1250. Like the North Rose Window, the South Rose Window reached 12.90 metres in diameter and, if you include its bay, a height of nearly 19 metres. This rosette is dedicated to the New Testament.
