Circe changing Ulysses's Men into Beasts

Traditionally the subject of this etching had been interpreted as an allegory of Melancholy, including by Adam Bartsch, but more recently scholars seem to agree on the identification of the figure as the sorceress Circe. Although there is no drawing or painting in the artist's oeuvre directly related to this print, Castiglione treated the subject repeatedly in different mediums. There is a rapid sketch depicting Circe at the Philadelphia Museum of Art (inv. no. 1984-56-39), a drawing in the Royal Collection, Windsor (inv. no. 904067), and a number of paintings, including one version in the Uffizi, Florence.
