 The madrāšê are gathered into various hymn cycles.Each group has a title — "Carmina Nisibena", "On Faith", "On Paradise", "On Virginity", "Against Heresies" — but some of these titles do not do justice to the entirety of the collection (for instance, only the first half of the "Carmina Nisibena" is about Nisibis).Each madrāšâ usually had a refrain (, "‘ûnîṯâ"), which was repeated after each stanza.
