The present work is based with slight variations on a picture by Sebastiano Conca now in the Bob Jones University Collection (Pepper, loc. cit, pp. 46-47, no. 46.2, illustrated p. 192; exhibition catalogue, 1985, pp. 274-275, no. 95a). That picture is itself a reduction of two large canvases, each representing a single figure, in Palazzo Lomellini-Balbi-Lambi-Doria, Genoa (see E. Schleier, 'Una decorazione poco nota di Sebastiano Conca a Genoa', Antichità Viva, 1980, XIX/3, pp. 20-26).
The attribution to the present painting to Costanzi was made by Anthony Clark.
