I used to take friends and colleagues to lunch at the Tate
Gallery (now Tate Britain). The food was good.
But the real reason that I went there was to see this
painting, An Experiment on a Bird in the Air Pump, by Joseph Wright of Derby.
He painted it in 1768.
In it, candlelit, a scientist with wild grey hair, an image
that was to become the very archetype, shows to a group of family and friends the
effects on a fluttering, panic-stricken white cockatoo of using an air-pump to
create a vacuum.
Will the bird live? The children are frightened – reassured
by their father(?). The boy on the left is absorbed in the experiment, but the
young couple (extreme left) are fascinated only by each other. Is the seated
pensive grey-haired man (extreme right) a second image of the scientist?
Through the window (top right) we see a full moon. This has
been interpreted as a reference to the Lunar Society, a group of men in the
English Midlands (centred on Birmingham) engaged in exploring the practical
potentialities of science.
They were friends of Joseph Wright and would together be a
major catalyst for the Industrial Revolution – among them the pioneering
manufacturer Matthew Boulton, Scottish engineer and inventor of the steam
engine James Watt, the great potter Josiah Wedgwood and Erasmus Darwin,
grandfather of Charles. Another member was Joseph Priestley, who discovered
oxygen just a few years after Wright painted this picture.
By the way, the painting has now returned to its proper
home, the National Gallery in Trafalgar Square.
