Time for an actual Venus on Venus Observations today. This lovely study by Boucher uses, as was not uncommon, a classical title as an excuse for showing a contemporary naked girl. The anatomical completeness of this shows that it was one of the many pictures he produced for "private collectors"; often using his wife as a model.
Boucher puts her bald mound dead centre in the composition and ensures that her vulva and the surrounding parts of her body are more brightly lit than her upper body, face and lower legs. It's quite clear what you are supposed to be thinking about!
