Sources and Interpretation
The narrative of those who gathered the blood of the Savior and of the martyrdom of Barypsabas appears in the Menologion of Basil II, compiled in the tenth century. The account is hagiographical and traditional, and the early details of the saint's origin and life are not otherwise documented.
Saint Nikodemos the Hagiorite offered an alternative reading of the tradition, suggesting that the blood and water in the vessel came not from relics of the crucifixion but from an icon of Christ whose painted side had been pierced. This interpretation reflects the cautious handling of the legend within later Orthodox tradition.
