                     Cathedral - Stained glass 
 
                    
                        
                            
                                
                                    
                                        
                                            
                                                
                                                    Among the
                                                          windows made originally for the cathedral are several in
                                                          the choir chapels, a large cycle of kings in the
                                                          clerestory and several in the north nave
                                                          aisle. Original
                                                          glass, notably from the triforium and choir chapels, was
                                                          removed in the 18th century in the course of a
                                                          redecoration program that replaced colored windows with
                                                          white glass. The five
                                                       windows of the original south aisle of the nave were also
                                                       removed at an unknown date. With the renewed interest in Gothic art
                                                       during the 19th century, medieval glass from several
                                                       secularized Cologne parish and monastic churches was
                                                       incorporated into the glazing of the cathedral, mainly in
                                                       the north transept and sacristy. The original decor can be partially reconstructed with the help of drawings made by
                   Sulpiz Boisserée.  The
                     burial of Archbishop Konrad von Hochstaden in the axial chapel in 1261 or shortly after gives
                     an approximate date for the ‘Bible window’ there.
 In many windows coats of arms help both to identify
                   their patron and to date the glass: for example, the arms of Heinrich von Virneburg in the cycle
                   of kings in the clerestory help to date them to his archiepiscopate between 1304 –
                   1332. Documents provide precise dates and names of the
                   patrons of the five north transept windows. Among the early glass the two ‘Bible windows’
                   are particularly important.

                                                       Kings is the oldest glass in the cathedral, and the earliest
                                                       preserved ‘Bible window’ in Germany. The second, originally from the Dominican
                                                       church and now in the St Stephen Chapel, reflects the
                                                       influence of French court painting.  The most important of the later
                                                         windows have been associated with such well-known Cologne
                                                         artists as the Master of St Veronica, the Master of the
                                                         Holy Kinship, the Master of St Severin, Bartholomäus Bruyn
                                                         the elder and those of the school of Stefan
                                                         Lochner.
 It is widely
                                                       assumed that this later glass was designed by one artist and
                                                       executed by others, so that the famous Cologne painters
                                                       themselves may have been responsible for some of the
                                                       designs. The comprehensive iconographic program has been
                   interpreted somewhat controversially by Rode as representing the History of Salvation, depicted
                   typologically with themes representing the three periods of history. Thus the period ante legem is represented by
                   Christ’s genealogy, as seen in the kings of the clerestory windows; the period sub lege is
                   depicted in the axial chapel of the choir in scenes of Christ’s life; and the period sub gratia
                   is depicted in the other choir chapels, in scenes from the lives of saints. A typological view of history is also worked out
                   in more detail in the two ‘Bible windows’, where scenes of Christ’s life are related to Old
                   Testament events. The depiction of Christ’s ancestors as kings, and the prominence of the scene
                   of the Adoration of the Magi in the axial window of the clerestory, have been associated with
                   the importance of CologneCathedral as the cathedral of the Three Kings |
