The artist, who was born in Naples and died in Madrid, studied in Venice and was one of the most important Venetian Rococo painters. He worked in Germany, London, Venice and Madrid and created numerous portraits. The lady is seated upright, turned to the left, with a self-confident but friendly gaze from large, grey-blue eyes towards the viewer. The light falls from the top left, illuminating her face and bust in particular. A small blue scarf lies on the white powdered hair of her wig and she wears a large pearl earring in her ear. The lady is wearing a light-coloured, slightly gold-shimmering silk dress with a lacy, deep and very wide neckline, from the edge of which white lace protrudes. A brooch is attached to the neckline. A wide, blue velvet coat with a purple lining is draped over her right shoulder and rests over her left forearm. The neutral brownish background behind the lady on the right is brightened by the light.
