Callisto raises her arm in horror as her companion nymphs reveal her pregnant form to the goddess Diana, on the left. Callisto had been seduced by Jupiter. As a result, Diana, goddess of the moon, hunting and chastity, banished her from her realm. The ample female figures are characteristic of Jordaens’s nudes. The drawing corresponds quite closely to a rectangular oil painting of the subject which Jordaens made in about 1640 (Private Collection).
