In fact, attributions regarding authorship vary according to interpreters. Particularly noteworthy is the similarity with the work entitled The Archdukes Albert and Isabella Visiting a Collector's Cabinet (The Walters Art Museum, Baltimore), attributed to Hieronymus Francken II.

A drawing made by the Bohemian gentleman Heinrich Hiesserle von Chodaw, who attented Drebbel's presentation of the perpetuum mobile to King James I in 1607, is perhaps the one that resembles the painted version most (Drake‐Brockman, Figure 2). 18. Drake‐Brockman, ‘Perpetuum Mobile’, 143–4. This mechanism for perpetual motion has been regarded as a predecessor of the barometer. Michel, ‘First Barometer.’ 19. Many are compiled in Rye, England as Seen by Foreigners, 232–42. 20. Drake‐Brockman, ‘Perpetuum Mobile,’ 137. 21. An interesting exception could be the painting entitled Allegory of Hearing, by Jan Brueghel the Elder and Rubens (Prado Museum, catalogue no. 1.395). One of the instruments on the wall (the second from the left), at the right‐hand side of the composition, seems to feature the distinctive ring‐shaped glass tube filled with liquid. This could be a model of perpetuum mobile rather different to those conventionally depicted. I was persuaded to look for a perpetuum mobile/clock‐like device in this painting after observing a perpetuum mobile in another Allegory of Hearing (Ertz, Breughel the Younger, 350, Figure 184) mentioned in Michel, ‘First Barometer’, 92, n. 7. Vera Keller has also noted this in her work on Drebbel. See Keller, ‘Cornelis Drebbel,’ 268. 22. I thank Simon Schaffer for his suggestions on accumulation and technology.
