gold and jewels. Of special interest is the gold shrine that used to contain the cloak of Mohammed. Miniature and Portrait Gallery Adjacent to the north of the Imperial Treasury lays the pages dormitory, which has been turned into the Miniature and Portrait Gallery (Müzesi Müdüriyeti). On the lower floor is a collection of important calligraphies and miniatures. In the displays, one can see old and very precious Qur'ans (12th to 17th centuries), hand-painted and hand-written in Kufic, and also a Bible from the 4th century, written in Arabic. A priceless item of this collection is the first world map by the Turkish admiral Piri Reis (1513). The map shows parts of the western coasts of Europe and North Africa with reasonable accuracy, and the coast of Brazil is also easily recognizable. The upper part of the gallery contains 37 portraits of different sultans, most of which are copies since the original paintings are too delicate to be publicly shown. The portrait of Mehmed II was painted by the Venetian painter Gentile Bellini. Other precious Ottoman miniature paintings that are either kept in this gallery, the palace library or in other parts are the Hünername, Sahansahname, the Sarayı Albums, Siyer-ı Nebi, Surname-ı Hümayun, Surname-ı Vehbi, and the Süleymanname among many others. Enderûn Library (Library of Ahmed III) The Neo-classical Enderûn Library (Enderûn Kütüphanesi), also known as "Library of Sultan Ahmed III" (III. Ahmed Kütüphanesi), is located directly behind the Audience Chamber (Arz Odası) in the centre of the Third Court. It was built on the foundations of the earlier Havuzlu kiosk by the royal architect Mimar Beşir Ağa in 1719 on orders of Ahmed III for use by officials of the royal household. The colonnade of this earlier kiosk now probably stands in front of the present Treasury. The library is an example of Ottoman architecture of the 18th century. The exterior of the building is faced with marble. The library has the form of a Greek cross with a domed central hall and three rectangular bays. The fourth arm of the cross consists of the porch, which can be approached by a flight of stairs on either side. Beneath the central arch of the portico is an elaborate drinking fountain with niches on each side. The building is set on a low basement to protect the precious books of the library against moisture. The walls above the windows are
