In Mesopotamian cosmogony Apsu is the freshwater primordial ocean that, together with the saltwater Tiamat, gives rise to earlier generations of gods (for example Lahmu and Lahamu). Apsu exists from the beginning of the cosmos as the subterranean and surrounding freshwater principle; in Enūma Eliš the younger god Ea perceives the threat Apsu poses to the new generation, slays Apsu, takes Apsu's halo, and Apsu's domain becomes the dwelling of Ea and Damkina. Enūma Eliš further locates the birth of Marduk 'in the heart of Apsu,' where Ea and Damkina beget him.
Primary texts emphasize Apsu as the primordial freshwater abyss and a hypostatic divine presence rather than offering a consistent anthropomorphic iconography. Enūma Eliš and related summaries describe Apsu as the subterranean fresh-water ocean/abyss; later references note symbolic attributes (for example a 'halo' taken by Ea) but no stable corporeal depiction is preserved in the supplied material.
Apsu functions cosmologically as the source and regulator of fresh water: lakes, springs, rivers, fountains, rain and, in flood narratives such as Atrahasis, the Flood itself are said to originate from the Abzû/Apsu. Mythically Apsu is a progenitor in the divine genealogy and, in narrative sequences, an actor whose death by Ea results in transfer of his domain and the placement of later gods; his agency thus ranges from sustaining life through water to being a locus and participant in theogonies.

Wards
None recorded.

Tiamat
The primordial salt-sea dragon of Babylonian creation myth — the chaos-mother from whose slain body the universe was built, and whose blood became the first humans.

Laḫmu
Laḫmu (Laḫamu for the feminine counterpart) is an apotropaic Mesopotamian supernatural being attested both as a class of protective attendants in ritual contexts and as an individual primordial figure in some theogonies (notably variants of the Enūma Eliš). Generally regarded as protective household and temple guardians, Laḫmu are also incorporated in certain mythic genealogies.

Lahamu
Lahamu is a minor primordial figure in Mesopotamian cosmological genealogies, attested in variants of the Enuma Elish and in some god-lists as a feminine counterpart to Lahmu and an ancestor in the lineage that leads to the major sky-god Anu. She appears in literary creation contexts rather than as a focus of cultic practice.
'Ain Samiya Goblet
Silver cup from the Middle Bronze Age I, discovered in a tomb at Ain Samiya. (Note: 1. Power tier should be "None", but add a note explaining that historical artifacts don't fit into the typical power tier classification. 2. Add a description of its appearance based on it being a sil)
A'annepada
A'annepada (Sumerian cuneiform 𒀀𒀭𒉌𒅆𒊒𒁕; also romanized Aanépàdda) is attested as a historical ruler of the First Dynasty of Ur, flourishing c. 2350 BC. He is recorded in dedicatory and foundation inscriptions as king of Ur and as son of Mesannepada, credited with temple-building and dedication to deities such as Ninhursag and Inanna.
Abu
Abu is a poorly understood Mesopotamian god attested in modern reference summaries. Secondary literature tentatively links him with vegetation and snakes and records that he was often paired with a deity written gu2-la2, but primary details about his cult, iconography, and myths are lacking in the cited sources.
Abzû
Abzû (Sumerian abzû; Akkadian Apsû) is the primordial freshwater abyss in Sumerian–Akkadian cosmology: the deep fresh waters that underlie and surround the earth, source of springs, rivers and ritual holy waters, and a creative principle whose mingling with the salt sea (Tiamat) figures in Mesopotamian cosmogony.
Abī-simtī
Abī-simtī (also rendered Abi-simti, Abisimti) is a named woman attested in third-millennium BCE Mesopotamian documentary and literary texts. She appears in administrative account records as a provider of animals and donor to temple cults and in Sumerian love-song literature as the named beloved/consort addressed by a royal speaker.
Adad
Adad (also Hadad, Haddad; Sumerian Iškur) is the storm- and rain-deity attested in ancient Mesopotamian and Canaanite religious contexts. Sources identify him as a principal weather god whose domain is storms and rainfall and whose name appears across multiple Near Eastern languages and sites, including Ebla (as Hadda, c. 2500 BCE).
Adapa
Adapa is a mythic figure from ancient Mesopotamian (Sumerian and Akkadian) literature: a mortal fisherman and temple sage of Ea at Eridu endowed with exceptional wisdom. He appears in a fragmentary tale in which he breaks the wings of the south wind and is summoned to the divine court; his name was later invoked in exorcistic and ritual contexts as an authoritative identity.
Adonis
Adonis is a mythic mortal youth in ancient Greek tradition, beloved by goddesses (notably Aphrodite and Persephone) whose death and seasonal return are the focus of the women’s midsummer festival Adonia. The cultic practices—planting short-lived 'gardens of Adonis' on rooftops, ritual lamentation, and casting an effigy and withered plants into the sea—symbolically link him to vegetation cycles and Near Eastern dying-and-regenerating god traditions.
Adrammelech
Adrammelech is attested in ancient Semitic textual tradition as a local god of 'Sepharvaim.' The name is commonly glossed as "Magnificent king." In modern times the name has been reused in diverse fictional, musical, and online contexts, but those are creative reworkings rather than continuations of the brief ancient attestation.
Aga of Kish
Aga of Kish (Aga, Agga, Akka) is an Early Dynastic Mesopotamian king recorded in the Sumerian King List, the Tummal Inscription, epigraphic objects, and the Sumerian poem "Gilgamesh and Aga." He functions in texts as a historical/legendary political actor who attempted hegemonic demands on Uruk and was ultimately captured and released by Gilgamesh.
Agasaya
Agasaya is presented in modern secondary sources as a little-attested Semitic war goddess who, according to some summaries, was later absorbed as the warrior aspect of the major Mesopotamian goddess Ishtar. The attestation in available materials is sparse and much inferences about her name, attributes, and later influence are explicitly marked speculative in those sources.
Agum II (Agum‑Kakrime)
Agum II (called Agum‑Kakrime in the inscriptionary tradition) is a Kassite-era Babylonian king known from the Agum‑Kakrime Inscription and later copies. He appears in Akkadian inscriptional and king-list traditions as a royal restorer who recovered and reinstalled the cult statue of Marduk and refurbished the É-sagila, presenting himself as a legitimate shepherd‑king and temple benefactor.
