The 18in (44cm) shallow dish – produced at the very advent of the art form in the 1480s – is a lost sibling to four similar large dishes made during the reign of Mehmet II ‘the Conqueror’ that were published in Nurhan Atasoy and Julian Raby’s landmark book Iznik: The Pottery of Ottoman Turkey (1989). 

It was formerly owned by the Alexandria-born bibliophile and businessman Max Debbane (1893-1965) and consigned for sale on October 24 from an American private collection.

Iznik dish

This 15th century Iznik dish was estimated at £300,000-500,000 at Sotheby's.

It attracted nine active bidders at its £300,000-500,000 estimate and at least three combatants on the phone prepared to go above £3m. The bidding contest, won by an institutional buyer, lasted a full 20 minutes.

The price ranks as the fourth highest ever for Islamic art at auction.
