Venerable Paphnutius of Egypt, father of St. Euphrosyne of Alexandria.
St. Paphnutius was a wealthy Christian of Alexandria in the fifth century whose only daughter Euphrosyne fled a worldly marriage to live in disguise as a monk. Tradition relates that he sought her for years, was consoled by the monk Smaragdus without knowing it was she, and learned the truth only at her deathbed.
He then took up her cell and lived there in asceticism until his own repose. He is commemorated with his daughter on September 25.
