Flag Germany Bavaria

The lonzenges are neither set in number, except there must be at least 21, and the top right (incomplete) lozenge must be white. Some people believe the lozenges to be representative of the lakes and rivers of Bavaria; or their color to be that of the lakes or the sky or both (as in the Bavarian anthem, which says 'die Farben seines [or "deines" ] Himmels, Weiß und Blau' - 'the colors of His sky/heaven, white and blue'); but this has never been proven. The other argument is that they are historical.
