To my eye, two features of the Gérôme's sculpted Omphale in this picture recall Rubens' (1.0018_Rubens): its being perched on a pedastal and the peculiar appearance of the lion's skin cushion under the queen's left arm.

The images at right show the finished painting and Gérôme's intermediate study.
