Advent Calendar Roman Window 8

This is an alabaster window from the Basilica of Saint Paul Outside the Wall.

Prepare the way, O Zion; your Christ is drawing near!
Let every hill and valley a level way appear.
Greet one who comes in glory, foretold in sacred story.
Oh, blest is Christ that come In God’s most holy name.
Advent Hymn # 65
