Waterloo Bridge, London at Sunset

A stone bridge quietly traverses the center of the canvas.
The sky and water are filled with shades of blue and green, while the arches of the bridge glow in pale pink.

Shrouded in a soft mist, it is an ethereal twilight scene.
At first glance, it appears to be a poetic work capturing a beautiful meteorological phenomenon woven by nature.

Yet in truth, this mist was not a creation of nature.
It was severe air pollution blanketing London at the height of the Industrial Revolution—
thick soot and smoke rising from domestic coal fires and raw coal burned in factories.
It was the infamous London smog.

In the autumn of 1899,
Claude Monet visited London.
He would return in the winters of 1900 and 1901.

He stayed in a sixth-floor room at the Savoy Hotel on the banks of the River Thames.
Looking east from his balcony, he could see the original Waterloo Bridge, opened in 1817.
Behind the stone bridge and its nine arches rose the smokestacks of an industrial district.

This urban pollution tormented residents and sullied the city.
Yet Monet was utterly captivated by this opaque atmospheric layer and the scattering of light it created.

"It is the winter fog that gives the city its true grandeur."

So he remarked in a later interview.
Without fog, London would not be a beautiful city;
it is the fog that gives London its magnificent scale.

To him, the smoke and smog were more than just a weather phenomenon.
It was a mysterious cloak that wrapped uniform structures,
transmuting man-made buildings and grimy factories into a fantasy of light.
For Monet, it became an indispensable artistic medium.

At dusk,
the sun sinks in the west, dyeing the bridge's piers in hues of red.
From his fixed viewpoint, Monet observed the scene and set to work on his canvas.
