Flash-fire of the final rays br Flames upon the walls br As if the battle rages again. br Intense light deep-shadows br The seams between boulder and boulder br And the pits in these irregular rocks - br Until the burning source recedes, br Leaving the wall ancient again: br Softer, flatter, br Bluing in the dusk. br br A pale moon, transparent as a shroud, br Rises above it, br Bleaching the battlement to bone br Under its luminous light.
