O Virgo virginum, quomodo fiet istud?
Quia nec primam similem visa es nec habere sequentem.
Filiae Jerusalem, quid me admiramini?
Divinum est mysterium hoc quod cernitis.
O Virgin of virgins, how shall this be?
For neither before you was any like you, nor shall there be after.
Daughters of Jerusalem, why marvel at me?
The thing which you behold is a divine mystery.
(Alternative Antiphon in English Medieval usage, up to and including the New English Hymnal)
O holy Virgin, Mother of our Lord, Theotokos, God-bearer, wondering maid among the dreaming daughters of an occupied city, waiting in the mystery you carry - pray for us!
