Who they were

Susanna the Deaconess (Ancient Greek: Σωσάννα ἡ διακόνισσα) was a deaconess, saint and martyr who supposedly lived in Palestine in the 4th century. According to her hagiography, she chose to devote herself entirely to the Christian faith by dressing as a man and joining a male monastery under the name "John". There, she led a pious life until she was discovered following false accusations of rape within the monastery.
