Puabi in the context of "Royal Cemetery at Ur"

Meskalamdug (𒈩𒌦𒄭, Meskalamdùg [mes-KALAM-du10] "hero of the good land"; fl. c. 2550 BC) was an early Sumerian ruler of the First Dynasty of Ur in the 26th century BCE. He does not appear in the Sumerian King List, but is known from a royal cylinder seal found in the Royal Cemetery at Ur, a royal bead inscription found in Mari, both mentioning him as King, and possibly his tomb, grave PG 755 at the Royal Cemetery at Ur.

It has been suggested that Puabi may have been his second queen.

A cylinder seal is a small round cylinder, typically about one inch (2 to 3 cm) in width, 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) in Syria, 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.
