At great pains and cost, Altstädtte, whole cities, have been rebuilt, stone by numbered stone, geranium pot by geranium pot. Photographically there is no way of telling; the patina on the gables is even richer than before. But there is something unmistakably amiss. Go to Dresden or Warsaw, stand in one of the exquisitely recomposed squares in Verona, and you will feel it. The perfection of renewal has a lacquered depth. As if the light at the cornices had not been restored, as if the air were inappropriate and carried still an edge of fire. There is nothing mystical to this impression; it is almost painfully literal. It may be that the coherence of an ancient thing is harmonic with time, that the perspective of a street, of a roof line, that have lived their natural being can be replicated but not re-created (even where it is, ideally, indistinguishable from the original, reproduction is not the vital form). Handsome as it is, the Old City of Warsaw is a stage set; walking through it, the living create no active resonance. It is the image of those precisely restored house fronts, of those managed lights and shadows which I keep in mind when trying to discriminate between what is irretrievable — though it may still be about — and what has in it the pressure of life.
