Washington D.C. 6/16/08"Scaffold" or "scaffolding" is one of my favorite words. It's ripe for metaphor, given it's positive connotations (supportive structure) and negative (criminal executions).
Scaffolds are useful and generally entirely utilitarian in design. Yet they can be beautiful in form even if the execution is crude. Repetition and symmetry are classical features of beauty in nature.
The relationship between a scaffold and a building is unbalanced but, again, symmetrical: the scaffold exists only to serve the needs of the more permanent structure, but is also necessary for the care and improvement of the building. The scaffold also obscures the design of the building, for which the scaffold may be resented and wished away.
To be a scaffold is to be required but unwanted, to serve only to be discarded. But a scaffold possesses one great and desirable trait: a purpose to which it is perfectly suited. We should all be so lucky.
