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
On the left is the small mosque of the black eunuchs. The tiles in watery green, dirty white and middle blue all date from the 17th century (reign of Mehmed IV). Their design is of a high artistic level but the execution is of minor quality compared to 16th-century tiles, and the paint on these tiles blurs.
