The figure of the page is similar to the one peering in the background of Judith with the Head of Holofernes, now in the Exeter Collection at Burghley House. The drawing for the page in the Burghley House picture, similar in technique to the present drawing, is at Windsor, O. Kurz, Bolognese Drawings of the XVII & XVIII Centuries in the Collection of Her Majesty the Queen at Windsor Castle, London, 1955, no. 494, fig. 92. A drawing for the same composition is also at Windsor, Kurz, op. cit., no. 493, fig. 91.
