During the third - early second millennium BC, as in other periods, different regional styles characterized pottery made in south-west, western, northern and south-east Iran. These seem to reflect flourishing regional areas. This is an example of a vessel which belongs to a long sequence of monochrome pottery found at sites such as Tepe Giyan and Godin Tepe. Such vessels, like this one, are mainly wheel-thrown jars and smaller vessels, generally painted with iron oxide fired to a dark brown colour. They bear an interesting range of intricate geometric designs. Other motifs include spread eagles: the use of motifs drawn from nature is a recurrent theme in ancient Iranian art.
