Karl - or Wilhelm?

heedless horseman, ride!
in your head the clouds stand still –
your steel steed’s hoofs fly

 Just in front of the DAZ is the Karlsplatz, where Saturday flea markets entice bargain hunters to the square of chestnut trees surrounding this memorial to Kaiser Wilhelm I. The square was named after Duke Karl Eugen in 1793, but the horse and rider have only been there since 1898, ten years after Wilhelm's death.
