Here’s a really cool post I found on the Design Observer site. It talks about this German Book from the 17th Century that basically is just a compilation of different calligraphy styles applied to the alphabet. What’s truly amazing is that each page gets more and more ornate. The time it took to make these is probably ridiculous, and I definitely don’t have a steady enough hand to do something like this so I definitely respect and admire it! Take a look.
I think it gets to a certain point where some of these are borderline-beyond-legible, but amazing to look at nonetheless!
