Belgian art dealer Klaas Muller has identified a previously unattributed oil-on-paper study as a work by Flemish master Peter Paul Rubens, titled "Bearded old man, looking down to his left" (ca. 1609). Muller purchased the piece for under €100,000 at a lesser-known northern European auction house three years ago, where it was listed as an unknown artist from the "Flemish school." After recognizing the bearded figure as Saint Thomas from Rubens's "Apostolado Lerma" series at the Prado, Muller commissioned research from art historian Ben van Beneden, former director of Rubenshuis, who confirmed the work's exceptional quality and likely attribution to Rubens. The study also features a ghostly woman's face visible when turned upside down, reflecting Rubens's playful reuse of materials.
