I follow Peter Webscott’s Wordscene blog with great interest. Peter and I have been in contact over the years and I bow to the superior, and original, quality of his work. Ravenna is one of my favourite places. A lovely city to visit, stuffed full of Byzantine treasures. The most marvellous mosaics in the world in my opinion (but then what would I know). I thought that you might enjoy this recent article from Peter, and perhaps spead a while looking around his blog, including a recent series about his visit to Mount Athos.
Read the article with superb photographs and excellent explanations here.
Byzantine Blog 
Hi Tom,
I am very touched by your kind words. Your blog has been an inspiration to me and I have enjoyed the many posts on a wide range of Byzantine related topics you have covered. I wish I wrote with your ease, but I have to write as best I can with what I’ve got!
Best wishes,
Peter
