A portrait by Willem Drost, 'The Sibyl' features a woman in a dimly lit setting, her gaze directed downwards, adorned with a jewelled headpiece and draped in a reddish-brown robe with a golden shawl.

Willem Drost (1633-1659) was a Dutch Golden Age painter, known for his history paintings and portraits. He was a student of Rembrandt, and his works often show the influence of his master's style, particularly in the use of chiaroscuro and dramatic lighting. Drost's career was relatively short, but he produced a number of significant works that demonstrate his skill as a painter. 'The Sibyl' depicts a woman in a dimly lit setting, her gaze directed downwards. She is adorned with a jewelled headpiece and draped in a reddish-brown robe with a golden shawl. The subject's face is softly illuminated, contrasting with the dark background, which creates a sense of mystery and introspection. The painting's composition and use of light are typical of Drost's style, reflecting the influence of Rembrandt's techniques. The sibyl, a figure from classical antiquity known for prophetic abilities, adds a layer of historical and mythological depth to the work.
