 There is some evidence that the Crusaders carried the reliquaries in front of their military campaigns as Byzantine emperors were known to have presented them.The Fieschi-Morgan Staurotheke is an example of Byzantine enameling dating to the early 9th century, though some suggest as early of a creation date as 700.It was quite possibly made in Constantinople, though there are debates around its origins, some suggesting it was made in Syria based on the inconsistencies in the Greek lettering.
