Ritual items carved of a gray- green stone in what is called the "Intercultural Style" were made in the greater Gulf area as well as in southern Iran. At the site of Tepe Yahya in Iran, workshops were found with vessels and the raw materials—chlorite or steatite—
for their manufacture, dating to the mid-third millennium B.C. The stones were available in the nearby hills. Fragments of containers were also found at sites in the Gulf area. Vessels decorated in this style were found across the ancient Near East from Syria to the Indus Valley, evidence of the flourishing long-distance trade of the times. The repertoire of motifs of the "Intercultural Style" includes vegetal, architectural, and abstract or naturalistic representations of people and animals. Many excavated examples have been found in palaces and temples or in graves of the privileged classes in major urban centers, including Sumerian (Early Dynastic) Mesopotamia. The vessels may also have been valuable for their contents.
