Keith Christiansen in The Jack and Belle Linsky Collection in The Metropolitan Museum of Art. New York, 1984, pp. 43–44, no. 11, ill. (color), discusses the subject in detail and Bacchiacca's four other versions of it; identifies the three children hatching from one egg in the present picture as Castor, Pollux, and Helen, and the two children at the left as Clytemnestra and Phoebe, based on Euripedes (Iphigenia at Aulus) and the medieval text known as the First Vatican Mythographer, as well as the fourteenth-century Ovide Moralisé, the last two of which state that Castor, Pollux, and Helen all emerged from a single egg; calls this painting the most individual and accomplished of the versions and believes it is also most likely to be the earliest.

PhD diss., Institute of Fine Arts, New York University, 2002, pp. 382–84, no. 36, suggests that the convex nature of the panel means that the painting served as a piece of furniture; argues that the figure of Leda is based entirely on Saint John's mistress in Dürer's print of the "Penance of Saint John Chrysostom," and also resembles Franciabigio's Bathsheba in his "David and Bathsheba" in Dresden; dates it to around 1525.

XXVIII, dates it to the end of the 1520s, after his other versions of this subject; attributes the I Tatti picture to the workshop; suggests that Bacchiacca painted series, such as the Leda pictures, "on spec, implying a marketing and exportation of art".
