Antiphon of Our Lady for Vespers from the Saturday before the first Sunday of Advent to the feast of the Purification, inclusive. It is ascribed to Hermann Contractus (1013-1054). There are several translations. The English title given is by D. Hunter-Blair; the first verse reads:
Mother benign of our redeeming Lord,
Star of the sea and portal of the skies,
Unto thy fallen people help afford -
Fallen, but striving still anew to rise.
