His Technique

Chiaroscuro, Italian for light-dark, is the art of building a picture from strong contrasts of illumination and shadow. Rembrandt absorbed it from his teacher Pieter Lastman and from the Dutch followers of Caravaggio, then made it entirely his own. Instead of lighting a scene evenly, he let a single source, a window, a candle or a hidden lamp, fall where the meaning lies, and allowed everything else to sink into a warm, breathing darkness.

In Philemon and Baucis the light source is hidden altogether. Mercury sits as a dark silhouette against its glow, while the light spills across the table and catches Jupiter's golden robe at the very moment the gods reveal themselves to their elderly hosts. Your eye goes exactly where Rembrandt wants it, and the shadows invite you to imagine what you cannot quite see.

Chiaroscuro and impasto were never ends in themselves. Rembrandt aimed his strongest light at faces and hands, the places where thought and feeling show, and gave those passages his richest, most worked paint, while costumes and backgrounds were left loose and dim. The result is a kind of guided attention: we look where he looked, and we stay there.

In the Self-Portrait of 1659, painted the year after his house and possessions were auctioned, light falls on a face built from dense, overlapping strokes, every furrow of the brow and pouch beneath the eye recorded without flattery. Nothing in the costume distracts. What remains is a man taking honest measure of himself, and it is that honesty, more than any trick of light, that makes his people feel alive nearly four centuries later.
