Sacred. If you have any interest in history, historical texts or the history of European culture, this is an exhibtion you really shouldn't miss. From a piece of the Dead Sea Scrolls to the most beautifully illuminated Qur'ans this is one of the most amazing collections of documents I have ever seen. If you can't make it to London then do have a look at the website because the British Library, as always, have done an excellent job of putting material online and have included some of the most spectacular in their Turning the Pages collection. They have also used Google maps to create an interactive map of some documents and there is a blog linked to the collection which includes thoughts from the learning team on taking young children around the exhibition. If you can make it to London before 23 September then go have a look for yourself, it's breathtaking and very thought provoking.
