Since designing the Bonifatius Church in Metzingen in 1956, Lothar Quinte had already created several larger church windows and gained artistic and craft experience, so that the conversion of painting into glass art, be it concrete or lead glass windows, had become routine for him. The collaboration with the Hamburg architect Horst Sandtmann on the redesign of the west facade of Lübeck Cathedral in 1963 turned out to be good, after initially some preliminary designs had been rejected. The result was a minimalist triptych with a 10 m high central window and two side, 9 m high, narrow, pointed-arched windows. The glass pieces in the side windows are horizontal, those in the middle high window are oriented vertically, creating a flow towards the center. The "mosaic" of many thousands of pieces of glass has the highest color intensity in the middle with a dominance of red, which decreases on all sides, where blue and yellow tones are more prominent. The result is a devout mood that is not based on representationalism, as was common in earlier centuries and is still desired in some cases today.
