Granulation was the art of decorating smooth surfaces of gold jewelry with patterns composed of tiny granules of gold. It was invented in Mesopotamia in the third millennium BC and was subsequently introduced to Anatolia, Syria, Egypt, Cyprus and Mycenaean Greece. The collapse of the Bronze Age civilization brought with it the disappearance of such sophisticated arts in Greece, but they survived in the Near East and from there they were reintroduced in Greece in the 9th century and transferred to Italy during the second half of the 8th century.
