Cylinder seal

A cylinder seal is a small round cylinder, typically about one inch (2 to 3 cm) in length, engraved with written characters or figurative scenes or both, used in ancient times to roll an impression onto a two-dimensional surface, generally wet clay. According to some sources, cylinder seals were invented around 3500 BC in the Near East, at the contemporary sites of Uruk in southern Mesopotamia and slightly later at Susa in south-western Iran during the Proto-Elamite period, and they follow the development of stamp seals in the Halaf culture or slightly earlier. They are linked to the invention of the latter's cuneiform writing on clay tablets. Other sources, however, date the earliest cylinder seals to a much earlier time, to the Late Neolithic period (7600-6000 BC), hundreds of years before the invention of writing. Cylinder seals are a form of impression seal, a category which includes the stamp seal and finger ring seal. They survive in fairly large numbers and are important as art, especially in the Babylonian and earlier Assyrian periods. Impressions into a soft material can be taken without risk of damage to the seal, and they are often displayed in museums together with a modern impression on a small strip. The cylinder seals themselves are typically made from hardstones, and some are a form of engraved gem. They may also use glass or ceramics, like Egyptian faience. Many varieties of material such as hematite, obsidian, steatite, amethyst, lapis lazuli and carnelian were used to make cylinder seals. As the alluvial country of Mesopotamia lacks good stone for carving, the large stones of early cylinders were imported probably from Iran. Most seals have a hole running through the centre of the body, and they are thought to have typically been worn on a necklace to be always available when needed. Cylinder-seal impressions served as an administrative tool, a form of signature, and for product branding. The cylinders themselves functioned as jewelry and as magical amulets; later versions would employ notations with Mesopotamian cuneiform.
