Anu- Mesopotamian GodDeity"Father of the Gods"

The Primordial Sky Father

Anu's Sumerian name, An, means simply "sky." The visible dome above was not a phenomenon but a divine being. In the earliest Sumerian theology, An was paired with Ki, Earth, as the primal cosmic couple whose union generated the other gods and all existence. The separation of An from Ki was one of the foundational acts of creation. In Gilgamesh, Enkidu, and the Netherworld, Enlil took the earth while An carried off the heavens.

The cuneiform sign for An, a star, became the determinative placed before the names of all deities. Every god's name in cuneiform bore the mark of the sky god.

The Sumerian King List opens with the declaration that kingship descended from heaven, from Anu's realm, before it was established in any earthly city. The first kings of Eridu, Badtibira, and Sippar ruled by Anu's dispensation, their reigns measured in fantastical numbers that blurred the boundary between divine origin and human history. Every subsequent dynasty held power only because kingship had first descended from Anu's heaven.

The Throne of Heaven

Anu presided over the divine assembly where the fates of gods and mortals were decided. He occupied the throne of ultimate authority among the Anunnaki, the great gods whose very name, "offspring of Anu," proclaimed their descent from him. In Sumerian art, his horned crown bore more tiers of horns than any other deity's. Other gods wore horned crowns too, but Anu's had the most horn-pairs, marking his supremacy in the visual grammar of divine iconography.

Yet Anu bestowed kingship more than he wielded it. Mesopotamian kings derived their legitimacy from this source, bearing titles like "beloved of Anu" and understanding their earthly thrones as reflections of his heavenly seat. The Code of Hammurabi's prologue names Anu first, the god who called Babylon's destiny.

The Tablets of Destiny, those cosmic records that determined all fates, derived their authority from Anu. When the monstrous bird Anzu stole these tablets from Enlil, Anu convened the divine assembly. God after god refused the mission to recover them. Finally Ninurta went, and after a battle that shook the mountains, he brought the tablets back and restored heaven's order.

The Bull of Heaven

The Bull of Heaven, Gugalanna, was Anu's creature, kept in the celestial realm until Inanna demanded it to destroy Gilgamesh after the king rejected her advances. Anu refused at first, warning that releasing the Bull would cause seven years of famine. But Inanna threatened to break open the gates of the underworld and let the dead outnumber the living. Anu relented.

The Bull descended upon Uruk. Its snorting opened great pits that swallowed hundreds of men. Enkidu seized it by the tail and Gilgamesh drove his sword between the base of its horns. Then Enkidu tore off the Bull's haunch and hurled it at Inanna. That act of sacrilege against Anu's sacred beast would cost Enkidu his life when the gods convened to decide punishment.

The Way of Anu

Mesopotamian astronomers organized the night sky into three bands: the Way of Anu along the celestial equator, the Way of Enlil in the northern sky, and the Way of Ea in the south. The MUL.APIN compendium, compiled around the twelfth century BCE and copied for centuries afterward, catalogued stars and constellations within this framework.

The movements of planets, the timing of eclipses, the color of the moon at its rising: all were read as messages inscribed by the sky god. Neo-Assyrian court scholars reported nightly astronomical observations to the king, framing their expertise as reading Anu's writing across the heavens. When an eclipse occurred at an unexpected time, priests performed substitution rites, and sometimes the king was removed from his throne until the danger passed.

Anu and Adapa

When the sage Adapa, first of Enki's seven apkallu, broke the wing of the South Wind while fishing in the Persian Gulf, Anu summoned him to heaven to answer for the assault. Enki prepared his protégé carefully. Adapa was to wear mourning garments and explain that he grieved for two gods, Dumuzi and Gishzida, who had vanished from the earth. When Adapa arrived at heaven's gate, these two gods stood as doorkeepers, and his show of grief on their behalf moved them to intercede with Anu.

The sky god was impressed by Adapa's wisdom, secrets that Enki had improperly revealed to a mortal. Anu offered him the bread and water of eternal life. But Adapa, following Enki's warning that the food and drink offered would be deadly, refused. Anu laughed. Enki had given his sage the knowledge of heaven and earth yet ensured he would remain mortal. Adapa returned to earth wise and destined to die.

The Succession of Power

In the earliest Sumerian texts, An held supreme power directly. As theology developed, Enlil assumed active governance while An retained titular supremacy. The Babylonian period saw a further transfer when Marduk rose as champion in the Enuma Elish. Even Anu could not face Tiamat and her monstrous army. The text says he "could not face her and turned back." Marduk succeeded where the sky god failed, and the fifty names of glory bestowed upon him included powers originally belonging to Anu. The sky god's authority was not destroyed but absorbed into the new supreme deity.

Among the Hurrians, the transfer was no peaceful delegation. In the Song of Kumarbi, Kumarbi overthrew Anu by biting off his genitals. From the swallowed seed, new gods were born. This violent succession myth passed through Hittite scribes into the Mediterranean world, where it surfaced in Hesiod's account of Kronos castrating Ouranos.

The Revival at Uruk

Anu's sanctuary, E-anna, the "House of Heaven," stood at Uruk from the earliest periods, though over centuries it became more closely associated with Inanna. But in the Seleucid period (312–63 BCE), Anu experienced a remarkable revival there. The great Bit Resh temple was rebuilt and lavishly maintained, and new ritual texts were composed detailing elaborate ceremonies for Anu and his consort Antu. Priests ascended to the temple rooftop at night to observe the rising of specific stars, welcoming them as manifestations of divine presence. Offerings of beer, dates, and roasted meats were presented to Anu's statue while hymns praised the sky god in language that consciously echoed compositions from a millennium earlier.

The Uruk scholars maintained detailed astronomical diaries recording planetary movements, eclipses, and atmospheric phenomena. They kept writing until cuneiform itself fell silent in the first century CE.
