The Attraction of Mountains

Back in Edinburgh now, but just can't resist one last snap  of Schiehallion, which has so dominated the landscape of our weekend up in Perthshire ...

... and thus; here's a poem, by Jon Plunkett, about the famous 1774 Schiehallion experiment and the compelling attraction of mountains:


The Attraction of Mountains

1 - Theory
An apple tree among the stars,
and from it a single apple falls.
It spins through the spheres,
draws a line straight and true.
A straight line, a true line, until -
from the planet’s rippled crust
a mountain rises, exerts a pull -
enough to sway that falling fruit.
 
2 - Mountain
In the heart of Scotland
a mountain of symmetry and bulk.
A shark’s fin of earth and stone
in and out of cloud, in and out of cloud
soaked and soaked again.
A place of ancient spirits, and new spirits –
illicit stills nestled by the burns
on this rock-crowned king of hills.

3 - Experiment
The measurements are minute,
fractions of fractions taken from the space
between a star-line straight and true, 
and a plumb-line’s slim deflection –
the most subtle bend of gravity,
the tiniest sway of cosmic force,
and just enough to weigh the world.

4 - Men
They are small, there on the hardship of the hill,
five hundred and fifty metres up
in bothies to house them and their tools.
Small, there on the flanks of a spinning planet.
And from this tangle of human complexities,
sharing small confines for weeks,
emerged – miraculously – 
the measurements needed.

5 - Results
Three hundred and thirty-seven 
observations of seventy-six stars.
Several hundred triangles
in various orientations.
Innumerable micro-measurements
of a plumb-line pulled.
From the maze of calculations
two things: the mountain 
depicted in concentric circles,
and the approximate weight 
of the world.

6 - Conclusion
Take a clear Schiehallion night
under an apple tree of stars.
Climb until you reach the smallest contour.
Climb until there is no more hill to climb
and there look up and know –
the world weighs more than first was thought
and this mountain will attract
always.
