That single act, on the night of 10 September 1509, is the reason he survived - because a few hours later, around ten in the evening, the floor of the Sea of Marmara wrenched sideways along the North Anatolian Fault and the bedchamber he had just left collapsed. Outside the walls of Topkapi Palace, an entire city was learning what its grandchildren would still call Kıyamet-i Suğra - the Lesser Day of Judgment.
