It is agitation and comfort at once: the night is enormous, and the night is watching over the houses. Strangest of all, the agitation is real physics. In 2006 researchers showed that the flicker of light across his most troubled-period paintings matches the statistics of turbulent flow, and in 2024 a study of the fourteen swirls found Kolmogorov's law of turbulence — written half a century after his death — hiding in the brushwork.

Theo paid for two small cells with barred windows — one to sleep in, one to paint in. From the bedroom he watched the dawn: 'This morning I saw the countryside from my window a long time before sunrise, with nothing but the morning star, which looked very big.' That star was Venus, truly blazing that spring. He was not allowed to paint upstairs, so around 18 June he built the night by daylight, in the studio below, partly from memory — real Venus, real Alpilles hills, an invented village, a cypress pulled close.

Two steam tugs moved it up the Thames on 5–6 September. Turner probably did not see that journey: the real hull was mastless, two tugs worked the tow, and it arrived before sunset.

Turner famously grabbed new factory-made colours almost as soon as the chemists produced them; the chrome yellows of the industrial age glow through this period of his skies. A popular story says this sky blazed with iodine scarlet, a gorgeous mercury red that dies in daylight, and was already fading by 1859 — yet the Gallery's own examiners call the sunset 'unusually intact', so hold that story loosely. And the Tambora legend fails here on arithmetic: volcanic reddening shows in paintings only for about three years after an eruption, and Tambora blew in 1815. This sunset needed no volcano.

Vermeer's great extravagance was blue: natural ultramarine, ground from lapis lazuli carried from Afghanistan, a pigment costlier than gold in the seventeenth century. Other painters saved it for a robe; Vermeer worked it into shadows, whitewashed walls, and gray mixtures of lead white, bone black and raw umber, so that his daylight glows in a way cheaper azurite never could. Around the blue sat a small, disciplined palette — lead-tin yellow for warm lights, madder lake for red glazes, green earth in shadowed flesh. The habit was ruinous arithmetic: exorbitant blue, perhaps three pictures a year, eleven children to feed. When he died in December 1675, aged 43, the baker held a bill of 617 guilders — roughly three years of bread — and his widow settled it with two paintings.",

In October 2020 the copy Mills College had owned since 1977 sold at Christie's New York for $9,978,000 — a record at auction for any work of literature. New ones still surface: in 2016 a three-volume copy annotated by the eighteenth-century editor Isaac Reed was authenticated at Mount Stuart, on the Isle of Bute. And they are stolen. Durham University's Folio vanished in 1998; a decade on, Raymond Scott walked it into the Folger stripped of its binding and title leaf, spinning a tale of friends in Cuba — eight years for handling stolen goods, and death in his cell in 2012. In 1940 a gang lifted Williams College's copy behind a fake professor's card; it came home within the year. Manchester's, taken in 1972, is missing still.",
