room houses the Topkapı Dagger. The golden hilt is ornamented with three large emeralds, topped by a golden watch with an emerald lid. The golden scabbard is covered with diamonds and enamel. In 1747, the Sultan Mahmud I had this dagger made for Nader Shah of Persia, but the Shah was assassinated in connection with a revolt before the emissary had left the Ottoman Empire's boundaries. This dagger gained more fame as the object of the heist depicted of the film Topkapi. In the middle of the second room stands the walnut throne of Ahmed I, inlaid with nacre and tortoise shell, built by Sedekhar Mehmed Agha. Below the baldachin hangs a golden pendant with a large emerald. The next displays show the ostentatious aigrettes of the sultans and their horses, studded with diamonds, emeralds and rubies. A jade bowl, shaped like a vessel, was a present of Czar Nicholas II of Russia. The most eye-catching jewel in the third room is the Spoonmaker's Diamond, set in silver and surrounded in two ranks with 49 cut diamonds. Legend has it that this diamond was bought by a vizier in a bazaar, the owner thinking it was a worthless piece of crystal. Another, perhaps more likely history for the gem places it among the possessions of Tepedeleni Ali Pasha, confiscated by the Sultan after his execution. Still more fanciful and romantic versions link the diamond's origins with Napoleon Bonaparte's mother Letizia Ramolino. Among the exhibits are two enormous solid gold candleholders, each weighing 48 kg and mounted with 6,666 cut diamonds, a present of Sultan Abdülmecid I to the Kaaba in the holy city of Mecca. They were brought back to Istanbul shortly before the Ottoman Empire lost control over Mecca. The gold ceremonial Bayram throne, mounted with tourmalines, was made in 1585 by order of the vizier Ibrahim Pasha and presented to Sultan Murad III. This throne would be set up in front of the Gate of Felicity on special audiences. The throne of Sultan Mahmud I is the centerpiece of the fourth room. This gold-plated throne in Indian style, decorated with pearls and emeralds, was a gift of the Persian ruler Nader Shah in the 18th century. Another exhibit shows the forearm and the hand of St. John the Baptist (Yahya), set in a golden covering. Several displays show an assembly of flintlock guns, swords, spoons, all decorated with
