Pope Stephen II
They are considered to be among the most notable of the many relics of the church; they are mentioned by Pepin the Short in the deed of 762, and he is said to have received them from Rome as a gift of Pope Zachary (741–752) and Pope Stephen II (752–757). Pope Zachary had recognized Pepin's election as king, and Pope Stephen II completed the gift in 754. Apart from its religious significance, the relic was the physical embodiment of the Frankish king's legitimation by the church.
