The tiniest wren that built her nest

In Christ's own halo, on Mary's breast,

Was scared away like a demon guest.

Once, twice, thrice, the glistening spire

That soared from the central tower, higher

Than all its clustered pinnacles, fell,

And not one of the carven saints could tell

The cause, though the emperor quizzed them well.

Down in the cloister all strewn with chips

Of alabaster and ivory tips
