What If Van Eyck’s Greatest Invention Was a Myth?

The Invention Jan van Eyck Never Made

Oil paint already existed. Van Eyck’s achievement was controlling how light behaved inside each painted surface.

The invention most often credited to Jan van Eyck was not his. Drying oils had bound pigments for centuries before he began painting. The Metropolitan Museum of Art traces oil painting in Northern Europe to at least the twelfth century. The turning point was the extraordinary control achieved by Van Eyck and other fifteenth-century Netherlandish painters.

A Layer Did Not Have One Job

Van Eyck organized color in stages. A white chalk ground, the prepared surface beneath the image, reflected light. Over it came an underdrawing, a preliminary design made with a brush. Opaque paint, which hides what lies below, established forms and colors. Transparent glazes then deepened them. A glaze is a thin paint layer that allows lower paint to remain visible.

Research into The Arnolfini Portrait found no exceptional pigments or binding media. The illusion depended on their use. The woman’s green dress has two opaque underlayers containing verdigris, lead-tin yellow, and lead white. Above them lies a transparent verdigris glaze in heat-bodied linseed oil with some pine resin.

Light reaches the solid layers and returns through the green glaze. The color can therefore appear deeper than a single flat mixture.

Different Surfaces, Different Paint

Technical examination of Margaret, the Artist’s Wife found that the red dress began with a thin, opaque vermilion layer over white chalk. Van Eyck modeled its folds with several transparent red lake glazes. A cross-section, a microscopic side view of a tiny sample, revealed three glaze layers.

Fur required another method. Van Eyck painted individual hairs mainly along the edges where the fur overlaps the dress and neckline. Our eyes complete the interior. On the white headdress, dense light touches create bright folds, while scraped lines and tiny strokes suggest thin linen.

Skin needed restraint. Research into Eyckian methods describes pale flesh built with thin layers that only partly cover the reflective white ground. This differs from impasto, paint applied thickly enough to rise above the surface.

Metal, glass, and jewels rely on carefully placed contrasts. In The Arnolfini Portrait, light forms dots on amber beads, passes through them as yellow crescents, and creates tiny reflections on the wall. In the Virgin of Canon van der Paele, pearls glow softly, faceted jewels flash, and polished armor contains distorted reflections.

Try This Principle

On a white prepared surface, establish a simple object with a thin opaque base. After it dries, add one transparent color layer. Reserve thicker, lighter paint for selected highlights. Compare something soft, such as fur, with glass or metal. Do not give them identical edges or brushstrokes.

Van Eyck’s lesson is not that every painting needs many layers. It is that every layer needs a purpose.

Learn to Think Through Layers

Traditional technique becomes less mysterious when each stage has a clear function. At Old Masters Academy, students explore underdrawing, underpainting, glazing, scumbling, and the balance between transparent and opaque paint using modern materials.
Online lessons let you pause at an important stage and revisit it while working on your own painting. Tutor critiques offer useful direction when a color seems flat or a surface does not yet feel convincing.

You can begin with no previous training or deepen skills developed over many years. Age and location do not determine whether serious artistic study is possible. Curiosity, practice, and thoughtful guidance matter more. Begin your artistic journey with Old Masters Academy and discover what carefully chosen layers can bring to your art.
