John of Würzburg
Also known as Johannes Wirziburgensis
German priest from Würzburg whose Latin Descriptio Terrae Sanctae records what he saw in Jerusalem under King Amalric I, with a famously chauvinist insistence on the German contribution to the kingdom's history.
John of Würzburg was a Franconian priest who travelled to the Holy Land sometime in the 1160s and dedicated his Descriptio Terrae Sanctae to a friend at home named Dietrich. He paced the streets of Jerusalem with a guidebook (probably a copy of Fretellus) in hand, recording the inscriptions that decorated the Holy Sepulchre and the Templum Domini, the new church of St Mary Latin, and the buildings of the Hospital — the last in a passage that is still the basic source for the size and routine of the Hospitallers in their first headquarters.
What gives the text its peculiar interest is John's editorial intrusion. He noticed, with audible irritation, that the inscriptions and other monuments of the kingdom attributed the conquest of 1099 almost wholly to the French contingents and said nothing of the Germans who had marched and died with them — Godfrey of Bouillon being credited as a French rather than as a German leader. His Descriptio is in part a polemic intended to put the Germans back into the historical record of 1099.
He is therefore a useful corrective to William of Tyre's smoother official narrative: a Latin clergyman of the second generation, walking the same streets as his French colleagues but reading the kingdom's monuments from outside its dominant nationality.
