Mamluk influence is observed in the oil lamps in the shape of hexagonal pyramids in a group of works typical of the period. The countless examples of such lamps, decorated with openwork, repoussé and intaglio and adorned with rumî and hatayî motifs, that have survived to our day show that they were produced abundantly in the second half of the 15th century. Candlesticks also occupy an important place among the metal work of this period.

THE ‘EHLİ HİREF’ OR OTTOMAN SCHOOL OF ART
Among the Ottoman metal work that has survived to our day, a plethora of objects dating to the period of Sultan Bayezid II stand out. Although Bayezid II’s passion for valuable objects has been viewed by historians as prodigal, its impact on art was positive, and it is a fact that the creation of new works was a compelling force in the encouragement and patronage of artists. The Ehli Hiref or craftsmen’s organization, which served as a school for every branch of Ottoman art, was established in this period.
