Most people visit Toledo to see pictures of El Greco, but a calligraphy enthusiast will find there something interesting, too. The Bible of Saint Louis, created in 13th century, is exhibited in the cathedral there. The book itself is exquisite, although its textura quadrata calligraphy is perhaps not the finest one can see. Still it a mediaeval book exhibited for everyone to be seen is not a common sight.
There is a book available, based on this blog.
On the blog there is, so to speak, more room, one can show more illustrations there. Blogs, however, come and go, there is no certainty that it will be there ten years from now. The book, on the other hand, once you acquire it, will last, one can be sure of that.
