Book excerpt: This gorgeous, full-color photographic guide reveals the marvelous collection of the sacred relics at the Topkapi Palace Museum in Istanbul, which houses more than 600 invaluable belongings from prophets such as Abraham, Moses, and Muhammad as well as a number of Muslim saints. Excavated from the most restricted rooms of the palace, the entire selection?including the pieces that are not on exhibit for daily visits?is compiled here for the first time in this fundamental handbook, making it perfect for students interested in Ottoman history, sacred relics of the Ottoman rule, or the broader Islamic heritage.
