JOSEPH WRIGHT OF DERBY: AN EXPERIMENT ON A BIRD IN THE AIR PUMP, 1768

He travels from town to town

with his apparatus;

a showman with wild white hair and incurious eyes,

he brings a touch of theatre to the lives

of squires and merchants, boys in love with death

and troubled girls who know this world is cruel

for reasons of their own.

Wherever he peddles his trade,

it’s always the same,

air pump and glass receiver, memento mori,

the flutter in the bowl just one more

instance of casual slaughter (tonight’s cockatoo

a rare and theatrical

flourish: more often he uses

some common or garden bird,

say a lark, or a sparrow).

While one hand works the pump, the other

hangs above the cover as the subject

struggles to stay alive,

a note of panic brightening the room

until the creature fades and what remains

is empty matter.

Lately, they’re all the rage,

these Pneumatical Engines,

amateurs build them at home, playing god for an hour,

owls in the deer park, a smatter of rain at the window,

the ticking of the clock, by which to time

the game of life and death:

I killed in the vacuum many

Animals that breath, as Birds, Mice, Rats,

Rabbets,

Cats;

some of them I recovered

by quickly giving them Air before

the Engine was quite exhausted;

but I never saw any revive,

that had been in a perfect vacuum.

One girl stares in fascinated

horror at the dying cockatoo;

another girl covers her eyes, while her father

points as if to say that grace will come

when the showman opens the vent – though grace delayed

is ever its own reward and, besides,

that well-dressed man in the foreground

is utterly rapt,

as is the boy

who might be his son and heir, their immaculate faces

half in the rouge-coloured shadows, their arms

akimbo, it seems, as they wait for the end to come:

but notwithstanding this hurt, the Lark

was very lively,

and did divers times spring up

to a good height.

The Vessel being hastily, but carefully closed,

the Pump was diligently plyed,

and the Bird for a while appeared lively enough;

but upon a greater Exsuction of the Air,

she began manifestly to droop

and appear sick,

and very soon after was taken

with as violent and irregular convulsions,

as are wont to be observed

in Poultry, when their heads are wrung off:

For the Bird threw her self over and over

two or three times,

and dyed with her Breast upward,

her Head downwards,

and her Neck awry.

The moon is full tonight, though we barely see it

up in the topmost corner, a sliver of cloud

bisecting it neatly, though nobody here can know

the world it illumines, the fox cubs crossing the lawn,

the owl floating out from the quincunx of elms in the park

and the silence that follows a kill, when everything stops,

that held breath over the land

till the dead move on.
