Jemdet Nasr: An archaeological site in central Iraq that gives its name to a late fourth-millennium BCE cultural period. Its excavated levels supplied the period’s defining archaeological sequence.
Cuneiform: A writing system used in ancient Mesopotamia, formed from wedge-shaped impressions on clay. Jemdet Nasr proto-writing precedes the mature system’s standardized cuneiform signs.
Three-age system: A broad archaeological framework dividing prehistory into Stone, Bronze, and Iron Ages. Its material-based divisions do not capture the fine regional chronology used for Jemdet Nasr.
Mesopotamian chronology: The framework for dating and sequencing the archaeological and historical periods of ancient Mesopotamia. Different chronological schemes place the period’s beginning and end somewhat differently.
Early Dynastic period: A Mesopotamian era, roughly 2900–2350 BCE, characterized by city-states and increasingly abundant written records. It follows Jemdet Nasr and makes its transitional position visible.
Ur: An ancient Mesopotamian city near the Euphrates, occupied from the fifth millennium BCE onward. Finds at Ur document material and administrative changes associated with this phase.
Clay tablet: A small slab of clay used as a durable writing surface in ancient Mesopotamia and neighboring regions. Administrative records from this period were commonly impressed or incised on clay.
Radiocarbon dating: A method for estimating the age of organic materials by measuring radioactive carbon decay. Absolute dating can test the period’s conventional calendar boundaries.
Archaeological culture: A recurring pattern of artifacts and practices used to classify archaeological evidence across places or time. Scholars debate whether shared Jemdet Nasr objects imply one coherent culture.
