Royal Day That Chaseth Gloom

Royal day that chasest gloom!
Day by gladness speeded!
Thou beheld’st from Mary’s womb
How the King proceeded;
Whom, true Man, with praise our choir
Hails, and love, and heart’s desire,
Joy and admiration;
Who, true God, enthroned in light,
Passeth wonder, passeth sight,
Passeth cogitation.

On the virgin as He hung,
God, the world’s Creator,
Like a rose from lily sprung—
Stood astounded nature:
That a maiden’s arms enfold
Him that make the world of old,
Him that ever liveth:
That a maiden’s spotless breast
To the King eternal rest,
Warmth and nurture, giveth!

As the sunbeam through the glass
Passeth, but not staineth,
Thus the virgin, as she was,
Virgin still remaineth:
Blessèd mother, in whose womb
Lay the light that exiles gloom,
God, the Lord of ages;
Blessèd maid! from whom the Lord,
Her own Infant, God adored,
Hunger’s pains assuages.

This appears to be an English translation of a medieval Latin hymn (likely 11th-13th century). The style and imagery are characteristic of sequences or hymns for Christmas or Marian feasts from the Sarum or Roman traditions. No specific author is identified in common hymnological sources; it is treated as anonymous or traditional. The partial third verse referencing the sunbeam through glass is a common medieval trope for the Virgin Birth.
