An oddity of TV period drama is how certain kinds of anachronism seem to be accepted as part of an authentic ambience even though they are clearly no such thing. Our notion of period authenticity seems to have been conditioned by museum visits and we forget that the things we see must have looked very different when new.
Early nineteenth century furniture in a Jane Austen drama should look fairly new but the wood usually has a rich patina which must have taken two centuries of polishing to mature. It should be much lighter, showing the original colour of the wood – possibly quite garish to our eyes.
We see heavily weathered Victorian brickwork which should look virtually new or the entrance to a stately home has sandstone pillars pockmarked with far too much age.
Leather-bound books which should look bright and fresh with gold lettering on the spine. Instead we see shelves full of books more akin to the interior of a modern antiquarian bookshop.
We often see china teacups in antique style but with modern backstamps. Alternatively mid Victorian teacups used in a nineteen thirties setting. Not impossible this one, but unlikely and...
...okay I admit it. Spotting these things is mildly enjoyable. How sad is that?
