Dish. Dimensions: 14 1/2 in. (36.8 cm). Date: second half 15th century.This striking turquoise-and-black bowl belongs to a group of ceramics known as Kubachi ware. Named for a village in the Caucasus where this pottery was discovered in quantity, Kubatchi wares may have been produced elsewhere in northwestern Iran. This bowl-- painted in black under a pale turquoise glaze, with an incised pattern of spirals and floral elements--is among the earliest examples. The bowl displays an inscription of wishes for good fortune. Museum: Metropolitan Museum of Art, New York, USA.
