This is one of the three large-scale Marian antiphons which survive from Tallisís early years; the others are Salve intemerata (RCM134) and Ave dei patris filia (RCM20). Elements of the composer's later style, particularly his melodic pithiness and ability to control a large structure, are already evident. For five voices: SATBarB. vii + 12 pages.
