I came across this painting of Marie-Antoinette and found it quite unusual. The Queen is cast in the role of Erato, the Muse of lyric (especially love) poetry. The painting, by Ludwig Guttenbrunn, is supposed to be dated 1788. Does anyone know what the circumstances were and why Marie-Antoinette would be portrayed in this guise? I was not able to find out much.
For comparison, here is a Roman statue of Erato. It strikes me that the classical image is much more austere. The painting seems so floral and decorative!
