Girl with a Pearl Earring

A girl turns to look at you. She wears a yellow and blue headscarf, a simple brown jacket, a large pearl earring. She is caught mid-turn, lips parted, eyes direct. The background is pure dark. She appears from nowhere, returns to nowhere. The composition is stripped to a single face and a single gesture: that turn.

The background was never empty. In 2018, the Mauritshuis research project used spectral imaging, X-ray fluorescence, and optical coherence tomography to examine every layer of the painting. They found it. A deep green curtain, painted with a mixture of indigo and weld, hung behind her. Over three and a half centuries, both pigments broke down chemically and faded to near-transparency. The darkness is not a compositional choice. It is what time does to certain colours.

The same investigation found delicate eyelashes, previously invisible beneath centuries of varnish. And along the edge of her headscarf, researchers identified pentimenti in the strict sense: small corrections where Vermeer adjusted the width and fall of the cloth, painting it one way, then painting over it to try another.

"The emptiness we have been reading as austere and modern is the decay of something that was once lush and green."

She is not a portrait. There is no known sitter, no commission record, no name attached to this woman in any document from Vermeer's lifetime. She is a tronie: a Dutch term for a character study, a painted type rather than a specific person. Vermeer made several. This one has eclipsed all of them.

The pearl itself is almost certainly not a real pearl. Pearls of that size would have been extraordinary. What Vermeer painted is a glass bead, probably, given a sheen by just two strokes of white paint on a dark ground. The entire earring is two brushstrokes. The lower one is the highlight. The upper one, less visible, anchors it.

• The earring is two brushstrokes. Look at it closely in any high-resolution reproduction. There is a small white comma of highlight and almost nothing else. The sense of a hanging, luminous sphere is created by implication, by the space around those two marks.
• The lower lip has a single dot of highlight. Just below centre. It is what makes the mouth look wet, slightly open, as if she is about to speak. Remove it in your mind and she becomes a different painting.
• The green curtain was always there. Every time someone called the dark background "bold" or "minimalist" or "modern," they were describing an accident of chemistry. The painting we know is not the painting Vermeer made.
