Gabrielle d'Estrées and one of her Sisters by one of the Masters of the Fontainbleu school, 1595

I have no idea what this painting is trying to convey as far as allegory is concerned. Leave it to the French to try something like this. Gabrielle is Henry IV's mistress and I have to say, that based on this painting, life in the d'Estrées household is one big party. Can't look at this painting without feeling tickly.
