What is "hieronymites"

The Order of Saint Jerome or Hieronymites (, abbreviated O.S.H.) is a Catholic enclosed religious order and a common name for several congregations of hermit monks living according to the Rule of Saint Augustine, though the inspiration and model of their lives is the 5th-century hermit and biblical scholar, Saint Jerome.

The principal group with this name was founded in Spain in the 14th century. Their religious habit is a white tunic with a brown, hooded scapular and a brown mantle. For liturgical services, they wear a brown cowl.
