A drawing in pen and brown ink and brown wash made in preparation for the second drawing in this pair was formerly with Galerie Martin Moeller, Hamburg (M.T. Caracciolo, op. cit., no. 49b). Maria Teresa Caracciolo dates the group to the 1780s, and suggests that a drawing of similar format and technique showing Athena inspiring a warrior to valour (sold Sotheby's, Monaco, 20-21 February 1988, lot 317) may be connected to the same unidentified project, perhaps for a frieze (M.T. Caracciolo, op. cit., p. 243).
