The British Museum holds a cylinder seal from Ur, circa 2100 BCE. When rolled across soft clay, it shows a bearded figure seated on a dais, a crescent moon hovering above his crown. That figure is Nanna, the moon god of Sumer. Nanna artwork refers to any visual depiction of this Mesopotamian deity, who also carried the Akkadian name Sin. In Sumerian and Akkadian art, he appears as a seated man with a long beard and a crescent moon, often accompanied by a bull or a boat. The images are not decoration. They anchored a god in stone, clay, and metal so he would see the supplicant, remember the name, and grant the petition.
The Earliest Surviving Images of Nanna
The oldest certain depictions of Nanna come from the Early Dynastic period (circa 2900–2350 BCE). A limestone relief fragment from Tell al‑Ubaid shows a bull-headed figure with a crescent on its brow; most scholars identify this as an anthropomorphic Nanna merged with his sacred animal. By the Akkadian period (2334–2154 BCE), cylinder seals habitually place Nanna on a throne with a crescent above his head, often facing a worshipper.
The most detailed early image survives on the Stele of Ur-Nammu (circa 2100 BCE, Penn Museum). The king approaches Nanna and the god extends a measuring rod and coiled rope, symbols of divine authority. Nanna’s beard is carved in vertical rows, his garment fringed, and the crescent floats at the level of his crown. The scene is not a story: it is a legal document carved in stone, recording that the god granted the king the right to build his temple.
What the Artwork Actually Showed: The Recurring Elements
The Crescent. Nanna’s primary attribute was the crescent moon, almost always placed above his crown or held aloft on a staff. In the earliest seals the crescent is horizontal; by the Neo‑Sumerian period (Ur III, 2112–2004 BCE) it often appears as a full‑circle with a gap, representing the new moon. The crescent was not merely an emblem. It was the god himself, present in the image.
The Bull. Many cylinder seals show Nanna seated on a bull or with a recumbent bull at his feet. The bull symbolized the full moon’s strength and the fertility the moon controlled. A lapis lazuli statuette of a bull, found at the Temple of Nanna at Ur, carries an inscription: “For Nanna, his lord, King Ur‑Nammu made this.” The bull is the god’s animal, not his pet. It is his power made visible.
The Boat. A distinctive motif in Nanna’s iconography is the moon‑boat (the coque céleste). Several seals from Larsa (circa 1900 BCE) show Nanna standing in a papyrus skiff, the crescent above him. This is the vessel that carries the moon across the night sky, an image shared with the Egyptian god Khonsu and the Greek Selene. The boat turns the moon’s movement into a ritual journey.
The Beard and Face. Nanna is always shown as a mature man with a long, squared beard. Unlike other Sumerian gods who might be depicted with wide eyes or fierce expressions, Nanna’s face is placid, almost expressionless. The moon does not change; it returns. This stillness is the divine quality the artist insisted on.
Why These Objects Were Made
Nanna artwork was never purely aesthetic. The vast majority of surviving images come from votive contexts: dedications left in temples asking for the god’s favor. A typical example: a small diorite plaque from Ur, now in the Iraq Museum, shows King Shu‑Sin of Ur (2037–2029 BCE) pouring a libation before a seated Nanna. The inscription reads “Shu‑Sin, king of Ur, king of the four quarters, his lord Nanna, for his life he made.” The plaque sits in the temple forever; the god sees it forever; the king’s life is remembered.
Cylinder seals worked the same way. When a person pressed their seal into the wet clay of a contract, Nanna was there as a witness. The image acted as a perpetual invocation. One seal from the reign of Amar‑Sin (circa 2046 BCE) shows a worshipper led by a goddess into the presence of Nanna; the inscription prays for the seal owner’s health. The image is the prayer.
The largest concentration of Nanna artwork comes from the Ekur‑igi‑gal, the temple complex at Ur excavated by Sir Leonard Woolley in the 1920s and 1930s. Woolley found hundreds of clay sealings, fragments of stone plaques, and a single massive copper‑alloy relief of a bull, all dedicated to Nanna. The hoard dates to the Ur III period (2112–2004 BCE), when Ur was the capital of a powerful empire and Nanna was the patron god of the state. The king was Nanna’s earthly steward, and the temple’s artwork was propaganda, devotion, and law rolled into one material act.
Symbolism That Survives the Empire
The symbols used by Sumerian artists continue to resonate in modern esoteric practice. The crescent and the bull appear in contemporary lunar altars, though the bull is often replaced by a bowl of water (following the moon’s connection to tides) or a horned animal figurine. The moon‑boat has been reinterpreted as a crescent‑shaped vessel for incense or offerings.
The number 30 is inseparable from Nanna. The Sumerians measured the lunar month as thirty days, and Nanna was called lugal‑30 (lord thirty). In artwork, the crescent with a full enclosure at a certain angle can represent the number 30. Modern practitioners who work with Nanna often place thirty small objects on their altar: thirty pebbles, thirty seeds, thirty drops of water, each one a silent count of the moon’s cycle.
Nanna’s association with the bull also ties him to the constellation Taurus, which in Sumerian astronomy was the celestial house of the moon. Some cylinder seals show Nanna holding a ring‑staff (a measuring tool) that doubles as a lunar‑phase indicator. The staff has seven notches, representing the seven days of the quarter‑moon. The image is a calendar.
Comparing Nanna Artwork with Other Moon Deities
Nanna is often grouped with the Egyptian Khonsu, the Greek Selene, the Norse Mani, and the Hindu Chandra. The differences in their depictions are instructive.
Khonsu is a child or a young man wearing a sidelock, with the same crescent and full‑moon disk. Nanna is never young: he is the father‑god, the king who gives legitimacy to earthly rulers. The art reflects a political role, not a cosmic one.
Selene is a woman driving a chariot. Her gender shifts her attribute: a torch or a veil instead of a bull. The bull in Nanna’s imagery is raw strength; Selene’s chariot conveys movement but not weight. The Babylonian moon god was heavy, seated, immovable.
Mani in Norse art rides a sled drawn by horses, chased by a wolf. There is no temple art of Mani, only poetic description. Nanna’s artwork is carved for houses of stone, meant to endure for centuries. The difference is liturgical: Sumerians needed the god to stay in one place, bound to the image.
Chandra in Hindu iconography rides a chariot drawn by ten white horses or holds a lotus and a club. The crescent is usually behind his head. Like Nanna, he is male and associated with fertility. But Chandra is never shown with a beard: the Indian moon god is youthful, ever‑renewed.
These comparisons show that Nanna artwork is distinctly regal. The beard, the throne, the bull, the king standing before him: the moon in Sumer was the guarantor of order, not a wanderer.
Common Misconceptions
“Nanna is female because the moon is feminine.” This assumption comes from European languages where the moon is feminine (Latin luna, Greek selene). Sumerian is not Indo‑European. Nanna is male; his wife Ningal is female. The triad of Nanna‑Utu‑Inanna (moon‑sun‑Venus) includes two male deities (moon and sun) and one female (Venus). The pattern does not match modern intuition.
“Nanna and Sin are different gods.” Sin is the Akkadian name for the same deity. In the Old Babylonian period (circa 2000 BCE) the names were used interchangeably. The city of Harran in northern Mesopotamia worshipped the god under the name Sin, and his iconography there is identical to that of Ur: crescent, bull, boat. There is only one moon god.
“Nanna artwork was only found in temples.” Thousands of private cylinder seals and personal amulets bear Nanna’s image. Every household that could afford a seal carried the god’s symbol into their daily transactions. The art was everywhere, not just in the ziggurat.
“The crescent always points upward.” Many early depictions show the crescent with horns pointing left or right. The orientation changed over time and did not carry fixed meaning. Some seals show a horizontal crescent, others a diagonal one. The point is the presence of the moon, not its angle.
FAQ
What does Nanna look like in Sumerian art? A seated bearded man wearing a flounced robe, with a crescent moon above his crown and often a bull at his feet. He holds a measuring rod and coiled rope on royal stelae.
Is Nanna a male or female deity? Male. His consort is Ningal. The Sumerian moon god is masculine, unlike the Greek Selene or Roman Luna.
What symbols are associated with Nanna? The crescent moon, the bull, the lunar boat, the number 30, and lapis lazuli. His sacred color is a deep blue, mimicking the night sky.
How was Nanna worshipped in ancient Mesopotamia? Through offerings of barley, oil, and animal sacrifice at his temple (the Ekur‑igi‑gal in Ur), and through votive plaques and seals that bore his image. The king acted as his representative.
Nanna’s face, carved into stone five thousand years ago, still meets the gaze of anyone who studies it. The crescent above his crown is the same crescent we look at tonight. For those who work with celestial deities, understanding how Nanna was seen is the first step toward seeing him yourself. The imagery is not art history: it is a technology of presence.
