A pendant to my post on black letter.

The key to this 1901 map, in case you can’t make it out in the German, is:

  • Blue: German alphabet (Fraktur)
  • Pink: Latin alphabet (Antiqua)
  • Pink with blue spots: Limited use of Fraktur alongside dominant Antiqua
  • Pink with yellow spots: Irish script alongside dominant Antiqua
  • Green: Cyrillic alphabet
  • Brown: Greek alphabet
  • Yellow: Arabic alphabet
  • White/grey: Kalmyk-Mongolian script

I’m not sure just where, if at all, that last one is to be found, but you’d expect it in the east and in the north Caucasus; but Turkey and North Africa are white too.
