Early Quranic manuscripts
The Topkapi manuscript is an early manuscript of the Quran dated to the early 8th century. This manuscript is kept in the Topkapi Palace Museum, Istanbul, Turkey. It was wrongly attributed to Uthman Ibn Affan (d. 656), but judging from its illumination, the Topkapi manuscript does not date from the period (mid 7th century) when the copies of the Caliph Uthman were written.
Topkapı Palace
A secret door behind a mirror allowed the sultan a safe passage. One door admits to the Queen Mother’s apartments, another to the sultan's hammam. The opposite doors lead to the small dining chamber (rebuilt by Ahmed III) and the great bedchamber, while the other admits to a series of ante-chambers, including the room with the fountain ("Çeşmeli Sofa"), which were all retiled and redecorated in the 17th century.
