The main field on this tile bears a dragon with its head turned back and a flaming pearl between its open jaws. The ground is filled with cloud scrolls reserved in lustre. Above it is a wide frieze with a lotus scroll. The tile is probably from the palace at Takht-i Sulayman built by the Ilkhan Abaqa Khan between 1270 and 1275. Tiles from the site are among the earliest recorded examples of the use of designs from Chinese sources in Ilkhanid art. Monochrome turquoise glazed brick or tile-work was first used to decorate exteriors of the predominantly brick architecture of Iran and Central Asia in the early twelfth century. By the beginning of the thirteenth century, cobalt blue and white were coming into use to enhance the range of colours but tile mosaic did not develop further till the revival of Islamic architecture following the conversion to Islam of Ghazan Khan in 694 AH (1295).
