Venerable Pambo the Hermit, desert father of Nitria.
St. Pambo was one of the great desert fathers of Nitria in Egypt in the fourth century, a disciple of St. Anthony the Great. Unlettered at first, he learned the Psalms and was known for his silence, his humility and his labor with his hands.
He reposed in peace, and his sayings are preserved among the Desert Fathers.
