Copies: one sold Galliera (Paris December 7, 1971) panel, 54 x 41; another by follower or studio w/ Gal. Pallamar, Vienna, 1968. Also one by Jan the Younger, with a few variations in table/ground area, in Pasadena, Norton Simon Museum. Preparatory drawing for this in British Museum (pen & ink, 25.5 x 35.6, signed).
Although Ertz has gone on/off about attribution here, others (Segal, Hairs, Brenninkmeijer-de Rooij) have OK'd it. Brenninkmeijer-de Rooij suggests a date of 1611-18. Ertz gives it a later date so that he can argue for Jan the Younger as assistant, but that is really not necessary. The original size of this painting is 46.5 x 33 cm (octagonal); it has since been altered to 52.5 x 43 cm.

A variation of this painting, executed by Jan Brueghel the Younger, is in Pasadena, Norton Simon Museum.
