Constantinople Pendant Reliquary Cross
This particular reliquary was believed to have been found in the ruins of the Great Palace of Constantinople, which was the royal residence of Byzantine emperors until the early eleventh century. Based on the costly materials and high quality of the workmanship, this reliquary most likely held a fragment of the True Cross or another Passion relic. The quality and material of a reliquary can inform us of not only the contents inside, but also the location of origin. The technique used to make it is called senkschmelz, which involves sinking enamelwork into a gold background. This method differs from earlier methods of fully enameled crosses (see Mosan Reliquary Cross). The changing artistic methods of reliquaries demonstrate the intermingling of artistic freedom and religious piety that is involved in creating reliquaries, which is influenced by the culture from which a particular reliquary was made.
