Evening Concert, Sainte-Chapelle

The celebrated windows flamed with light
directly pouring north across the Seine;
we rustled into place. Then violins
vaunting Vivaldi’s strident strength, then Brahms,
seemed to suck with their passionate sweetness,
bit by bit, the vigor from the red,
the blazing blue, so that the listening eye
saw suddenly the thick black lines, in shapes
of shield and cross and strut and brace, that held
the holy glowing fantasy together.
The music surged; the glow became a milk,
a whisper to the eye, a glimmer ebbed
until our beating hearts, our violins
were cased in thin but solid sheets of lead.

— John Updike
