As for the larger portion of the lance, Arculpus claimed he saw it at the Church of the Holy Sepulchre around 670 in Jerusalem, but there is otherwise no mention of it after the sack in 615. Some claim that the larger relic had been conveyed to Constantinople in the 8th century, possibly at the same time as the Crown of Thorns. At any rate, its presence at Constantinople seems to be clearly attested by various pilgrims, particularly Russians, and, though it was deposited in various churches in succession, it seems possible to trace it and distinguish it from the relic of the point. Sir John Mandeville declared in 1357 that he had seen the blade of the Holy Lance both at Paris "and" at Constantinople, and that the latter was a much larger relic than the former; it is worth adding that Mandeville is not generally regarded as one of the Middle Ages' most reliable witnesses, and his supposed travels are usually treated as an eclectic amalgam of myths, legends and other fictions. "The lance which pierced Our Lord's side" was among the relics at Constantinople shown in the 1430s to Pedro Tafur, who added "God grant that in the overthrow of the Greeks they have not fallen into the hands of the enemies of the Faith, for they will have been ill-treated and handled with little reverence."
