Marina of Aguas Santas was a second-century Christian martyr who lived in the Romanized regions of Galicia. According to tradition, she was raised in a rural setting where she embraced the Christian faith, leading to a conflict with her father. Her life is often described through a blend of historical accounts and legendary narratives, including versions where she was one of several sisters. She was eventually executed for refusing to renounce her religious beliefs, an act that reportedly caused water to spring from the ground at her place of death.
