Sumerian Lapis Lazuli Cylinder Seal

Early Dynastic II to III, c. 2700–2350 BC,  

Size: 5/8 inches (2 cm) L. Intact. 

Provenance:  Collection of David and Beverly Hall Billings, Nantucket, Massachusetts.

The composition shows a dense, all-over interlocking criss-crossing contest or animal frieze which fill is the full height of the seal without a clear ground line or seated deity, characteristic of the Early Dynastic brocade style.  Comparable to published lapis examples at the Met, British Museum.  Pierced for suspension.  

Cylinder seals served multiple crucial functions in ancient Mesopotamian society:
They acted as personal identification and professional credentials. They authenticated transactions and documents, similar to a modern signature. They prevented unauthorized access to containers and buildings.  They functioned as protective amulets and symbols of personal identity.
The use of lapis lazuli for this seal was deeply significant for several reasons:  Lapis lazuli was considered a divine material associated with the night sky and celestial realm.
The stone was believed to facilitate communication between mortals and deities.
In Mesopotamian cosmology, lapis lazuli was thought to be a constituent element of the physical night sky.  The stone's rarity and importation from distant Afghanistan made it highly valuable.  Its use in official seals demonstrated the owner's elevated social status.
The deep blue color with gold pyrite flecks symbolized success and divine connection.
Lapis lazuli's hardness made it suitable for detailed carving and repeated use and the stone's distinctive appearance helped prevent forgery. Its smooth surface allowed for clear impressions in clay.

The combination of a cylinder seal's administrative importance with the sacred properties of lapis lazuli created a powerful symbol of authority and divine sanction in ancient Mesopotamian society
