We are grateful to Dr. Philip Conisbee for confirming the attribution.
Florence Ingersoll-Smouse illustrates an engraving in the opposite sense, by F. Berardi, which corresponds closely to the present composition (Joseph Vernet, peintre de marine, Paris, 1926, p. 48, no. 1247 and fig. 289). She also illustrates an engraving after a possible pendant (op. cit., no. 1247 and fig. 288), and dates both these compositions to Vernet's Italian period.
