The antiphon Assumpta est maria appears in the Cistercian rite as a Lauds antiphon for the Feast of the Assumption of the Virgin. This one comes from a late-sixteenth-century choirbook that belonged to the feminine Cistercian monastery of S. Bento de Cástris in the outskits of Évora.
The melody has some variations from the modern version used, following the Liber Usualis. The version Ensemble Eborensis presents comes from the choir book P-EVad Mús. Lit. 35, now preserved in Évora Districtal Arquive.
This recording come from Ensemble Eborensis’s concert in the Church of Aguiar (a small village near Évora) last June 10th, where the group performed a programme made of Cistercian plainchant with 17th-century polyphony from Évora Cathedral.
