This video is a bit longer than usual, but I encourage you to take the time and savor this ancient melody. See the English translation below.
Virga ac Diadema
O branch and diadem
of the king’s purple,
you who are in your enclosure
like a breastplate:
Burgeoning, you blossomed
after another fashion than Adam
gave rise to the whole human race.
Hail, hail from your womb
came another life
of which Adam had stripped his sons.
O flower, you did not spring from dew
nor from drops of rain
nor did the air fly over you,
but the divine radiance
brought you forth on a most noble branch;
O branch, God had foreseen your flowering
on the first day of his creation
and he made you for his word.
As a golden matrix,
O praiseworthy Virgin.
