Philothei of Athens was a 16th-century Greek Orthodox nun and abbess born Revoula Benizelos. Born into a wealthy Athenian family in 1522, she later dedicated her life and inheritance to religious and charitable pursuits. She established monasteries and numerous social institutions, including schools and hospices, to serve the community. Her commitment to freeing enslaved Greeks from Ottoman rule led to significant hardship and eventually to her death following a violent assault. She is honored as a martyr and a patron of Athens.
