A study in reverse for the fresco datable to 1656-57 in the Palazzo Quirinale, Rome (Fig. 1; F. Petrucci, Pier Francesco Mola (1612-1666): Materia e colore nella pittura del '600, Rome, 2012, no. D24, pp. 81-5, 462-67). A drawing which is closer to the composition of the fresco is at Holkham (Inv. 15694; R. Cocke, op. cit., pl. 61). Five further studies in pen and brown ink exploring the composition are known (see R. Cocke, op. cit., pls. 65, 66, 71 and 72, F. Petrucci, op. cit., pp. 466-67 and Sotheby's, London, 2 July 1984, lot 64). The artist also explored different elements of the composition in a number of drawings (see R. Cocke, op. cit., pls. 63, 64, 67-70 and F. Petrucci, op. cit., pp. 466-67).
We are grateful to Nicholas Turner for confirming the attribution to Pier Francesco Mola after examining the drawing in person, and for his help in cataloguing it.
