Crudelis Herodes - Gregorian Chant - Vespers Hymn for Epiphany - Roman

Here's the updated (1632) Vespers Hymn for the feast of the Epiphany. It's taken from the longer hymn **A solis ortus cardine** which has a verse beginning with each letter of the alphabet. Unfortunately the update changes the first letter, which kinda defeats the purpose, but the Humanists thought it better that way. Compare and contrast:

1. Crudelis Herodes, deum
Regem venire quid times?
Non eripit mortalia,
Qui regna dat caelestia.

2. Ibant magi, quam viderant,
Stellam sequentes praeviam:
Lumen requirunt lumine,
Deum fatentur munere.

3. Lavacra puri gurgitis
Caelestis Agnus attigit;
Peccata, quae non detulit,
Nos abluendo sustulit.

4. Novum genus potentiae,
Aquae rubescunt hydriae,
Vinumque jussa fundere
Mutavit unda originem.

5. Jesu, tibi sit Gloria,
Qui apparuisti gentibus,
Cum Patre et almo Spiritu
In sempiterna saecula. Amen.

English:

WHY, impious Herod, vainly fear
that Christ the Saviour cometh here?
He takes no earthly realms away
Who gives the crown that lasts for aye.

To greet His birth the Wise Men went,
led by the star before them sent;
called on by light, towards Light they pressed,
and by their gifts their God confessed.

In holy Jordan's purest wave
the heavenly Lamb vouchsafed to lave;
That He, to whom was sin unknown,
might cleanse His people from their own.

New miracle of power divine!
The water reddens into wine:
He spake the word: and poured the wave
in other streams than nature gave.

All glory, Lord, to Thee we pay
for Thine Epiphany today;
all glory as is ever meet,
to Father and to Paraclete. Amen.
