File talk:St Denis North a.jpg
This image shows the south, rather than the north, transept rose at St-Denis edit
The north transept rose at St-Denis was installed c. 1250 and portrays the genealogy of Christ in a 'Tree of Jesse'. The south transept rose dates from c. 1260 and shows the Gregorian calendar and signs of the Zodiac. It appears as if these have been confused in the title and description of this file.
