Letting Light In

Brick by brick we built the walled protection,

Apertures, slit-crossed, for more defence,

Moated lakes surrounding valued castles

Or maybe simple whited picket fence.

Bit by bit we fenestrated wider,

Casements swinging freely to the air,

Still the walls enclosed, obscuring vision,

Justified, of course, for need of lair.

One day, perhaps, when bastions are French-glazed,

Doors that open wide, encircling, global round,

Maybe then the arrows will be quiver’d,

Eureka moment, Archimedes proud.
