I've had a tab, with this ebook, opened in my browser for quite some time. I need to close it. So, here, in brief, is the ebook. It's
free.
Byzantium: Faith and Power (1261-1557). Helen C. Evans, Editor. Co-published by The Metropolitan Museum of Art and Yale University Press. 682 pages. Lots of beautiful pictures and lots of closely spaced text in a small font (so, in other words, there's
lots of text).
Go to
this webpage to download it (only PDF available).
