Tomás Luis de Victoria (1548-1611)
O magnum mysterium
et admirabile sacramentum
ut animalia viderent Dominum natum
jacentem in praesepio.
Beata Virgo cujus viscera
meruerunt portare
Dominum Christum. Alleluia.
O great mystery
and wonderful sacrament
that even the animals saw the new-born Lord
lying in a manger.
Blessed Virgin, whose womb
was worthy to bear
our Lord Christ. Alleluia.
