The Book of Exits, miraculously copied

Here in this convent by an angel’s hand,

Stands open on a lectern, grooved

Like the breast of a martyred deacon.

The bishop has ordered the windows bricked up on this side

Facing the fields beyond the city.

Lit by the glow from the cloister yard at noon

On Palm Sunday, Sister Custos

Exposes her major relic, the longest

Known fragment of the Brazen Serpent.

True stories wind and hang like this

Shuddering loop wreathed on a lapis lazuli

Frame. She says, this is the real thing.

She veils it again and locks up.

On the shelves behind her the treasures are lined.

The episcopal seal repeats every coil,

Stamped on all closures of each reliquary

Where the labels read: Bones

Of Different Saints. Unknown.

Her history is a blank sheet,

Her vows a folded paper locked like a well.

The torn end of the serpent

Tilts the lace edge of the veil.

The real thing, the one free foot kicking

Under the white sheet of history.
