Max Goering. Letter. April 1938, calls it Neptune as commander of the winds and identifies Jupiter and Juno in the background; calls it a sketch for a ceiling.
Hermann W. Williams Jr. "Tiepolo and His Contemporaries." Metropolitan Museum of Art Bulletin 33 (March 1938), p. 64, notes that the project for which this is a sketch was apparently never carried out.

Alice Binion in Masters of the Loaded Brush: Oil Sketches from Rubens to Tiepolo. Exh. cat., Knoedler. New York, 1967, pp. 58–59, no. 44, pl. 44, suggests that the contrast between the elaborate Neptune group and the less finished forms of the rest of the picture might indicate a ceiling conception abandoned midway; notes that the figure of Neptune is "a near replica" of the one on Tiepolo's ceiling of the throne room in the royal palace, Madrid; rejects the idea that it could be a first idea for the ceiling in the hall of the Royal Guard, which also depicts the story of Aeneas; states that the winds in this work duplicate those in Tiepolo's ceiling in the Iphigenia room of the villa Valmarana.

Catherine Whistler. "Review of Gemin and Pedrocco 1993." Burlington Magazine 137 (September 1995), p. 626, suggests that it depicts "Juno ordering a seastorm to destroy the Trojan fleet," noting that this subject was depicted on the ceiling of one of the apartments of the Princes of the Asturias in the royal palace, Madrid, by Mariano Salvador Maella (ca. 1766, now covered by a false ceiling).
