Sarah the Martyr was a Christian woman from Antioch who lived during the early 4th century. During the persecutions led by Emperor Diocletian, she traveled from Syria to Egypt with her two sons. Fearing they might drown in a storm before they could be formally baptized, she performed a ritual using her own blood to mark them. This act of devotion led to her eventual martyrdom when she refused to renounce her faith upon returning home.
