A carved waterslide, India, circa 19th century. Estimate £2,000–3,000.

LONDON – In the elaborate designs of Indian formal gardens, waterslides were often used to create pleasing cascades of water. The surface of this white marble waterslide is adorned with beautifully sculpted fish, lizards and frogs. They are rendered with such skill that they appear to be caught, frozen, in an instant in time – the frog at the centre of the piece has just caught a worm.
