Medieval historians are faced with the daunting task of having to piece together around a thousand years of history without all that many written sources to speak of.

This week, Danièle speaks with Thomas Smith about letters from the First Crusade, which ones are either partially or completely invented, and what this discovery means to our understanding of the Crusades.
