Also called the Jeronymites or the Hierohymitae. Groups of hermits who followed the way of life of St. Jerome (342-420), going back to the community of men and women who gathered around him in Bethlehem. They were later given the Rule of St. Augustine. Hieronymite nuns were founded in Spain in 1426. In the sixteenth century the order was one of the channels through which the Catholic Counter-Reformation found its expression.
