Marble Throne, Diwan-i-Am (public audience hall). “The Diwan-i-Am (Hall of Public Audience) is a rectangular hall, three aisle deep, with a façade of nine arches. At the back of the hall is an alcove, where the royal throne stood under a marble canopy, with an inlaid marble dias below it for the prime minister. The wall behind the throne is ornamented with beautiful panels of pietra dura work, said to have been executed by Austin de Bordeaux, a Florentine artist.”
