Wedding the Locksmith's Daughter

The slow-grained slide to embed the blade 
of the key is a sheathing,
a gliding on graphite, pushing inside
to find the ribs of the lock.

Sunk home, the true key slots to its matrix;
geared, tight-fitting, they turn
together, shooting the spring-lock,
throwing the bolt. Dactyls, iambics--

the clinch of words--the hidden couplings
in the cased machine. A chime of sound
on sound: the way the sung note snibs on meaning

and holds. The lines engage and marry now,
their bells are keeping time;
the church doors close and open underground.
