The notable German historian and monk Ekkehard of Aurach was also a crusader. He wrote a comprehensive world history text, but upon returning from a pilgrimage to Jerusalem in 1101, he rewrote his portion on the First Crusade. "On the Opening of the First Crusade" is an excerpt from his larger work on the war, titled Hierosolymita. Modern scholars of history hold his contributions in high respect for hismeticulous attention to detail and broad scope.
