Byzantine Passion relics move to Paris

Relic transfers to Louis IX lead to the building of Sainte-Chapelle.

Documented transfers provide a comparison for how relics moved from Constantinople to western treasuries. The Shroud is not securely identified in these transactions.

In the thirteenth century, Louis IX of France acquired a group of Passion relics from Constantinople, including the Crown of Thorns and fragments associated with the Passion. The transfers involved political and financial negotiation with the Latin emperors and the Byzantine court. The relics were brought to Paris and became part of the Capetian monarchy’s sacred collection.¹

What the surviving source says

The surviving purchase and transfer records identify particular relics and their custodial setting. They are useful precisely because they show what a documented relic transaction can look like. The Turin Shroud is not securely named in this dossier, and it should not be added to the Paris group on the basis of a generic reference to linens.¹²

Historical significance and limits

The episode gives a strong comparative case for medieval relic mobility: named objects, political agents and a destination can be traced. It does not fill the Shroud’s own missing interval.²³
