 Bede reports that Hwaetberht had himself made a pilgrimage to Rome, "and had stayed there a good long while, learning, copying down and bringing back with him all that he thought necessary for his studies" during the papacy of Sergius I (687–701).Bede's "De temporum ratione" is dedicated to Hwaetberht, so Bede appears to have regarded him highly.A letter from Saint Boniface to Hwaetberht dated to circa 747 has survived in the Boniface Correspondence, placing Hwaetberht's death after that date.
