Where Spoor meets other subjects
With the printing press the Bible could for the first time be read in large numbers and in people's own language. That changed Europe.
Painters in Bruges and Ghent showed depth and light with astonishing precision. Looking at their work is art and history at once.
Who wrote this, when and why? Historians have asked these questions for centuries. They work just as well for a message on your phone.
