A chapel at Heiligenblut in the Duchy of Carinthia was first mentioned in 1271, containing a relic of the Blood of Christ. According to legend, a flask of the Holy Blood, which is today kept in a sacrament house, was brought here in 914 AD from the Hagia Sophia in Constantinople by a Danish knight called Briccius (Frederick, not to be confused with Saint Brice), once in the service of Emperor Constantine VII. On his way home across the Alps, he was buried by an avalanche and in the face of death hid the relic in an open wound at his calf. His corpse was later found by local peasants at a place where three ears of wheat broke through the snow—as rendered in the Heiligenblut coat of arms.
