Nabu (Akkadian: 𒀭𒀝, romanized: Nabû, Jewish Babylonian Aramaic: נְבוֹ‏, romanized: Nəḇo) is the Babylonian patron god of literacy, scribes, wisdom, and the rational arts. He is associated with the classical planet Mercury in Babylonian astronomy.

Ancient Mesopotamian religion encompasses the religious beliefs (concerning the gods, creation and the cosmos, the origin of humanity, and so forth) and practices of the civilizations of ancient Mesopotamia, particularly Sumer, Akkad, Assyria and Babylonia between circa 6000 BC and 500 AD. The religious development of Mesopotamia and Mesopotamian culture in general, especially in the south, were not particularly influenced by the movements of the various peoples into and throughout the general area of West Asia. Rather, Mesopotamian religion was a consistent and coherent tradition, which adapted to the internal needs of its adherents over millennia of development.

The earliest undercurrents of Mesopotamian religious thought are believed to have developed in Mesopotamia in the 6th millennium BC, coinciding with when the region began to be permanently settled with urban centres. The earliest evidence of Mesopotamian religion dates to the mid-4th millennium BC, coincides with the invention of writing, and involved the worship of forces of nature as providers of sustenance. In the 3rd millennium BC, objects of worship were personified and became an expansive cast of divinities with particular functions. The last stages of Mesopotamian polytheism, which developed in the 2nd and 1st millennia BC, introduced greater emphasis on personal religion and structured the gods into a monarchical hierarchy, with the national god of each state being the head of the pantheon. Mesopotamian religion finally declined with the Christianization of Mesopotamia between the 1st and 5th centuries AD.

Marduk (/ˈmɑːrdʊk/; cuneiform: 𒀭𒀫𒌓 AMAR.UTU; Sumerian: amar utu.k "calf of the sun; solar calf"; Hebrew: מְרֹדַךְ, Modern: Merōdaḵ, Tiberian: Mərōḏaḵ) is a god from ancient Mesopotamia and patron deity of Babylon who eventually rose to prominence in the 1st millennium BC. In Babylon, Marduk was worshipped in the temple Esagila. His symbol is the spade and he is associated with the Mušḫuššu.

By the 1st millennium BC, Marduk had become astrologically associated with the planet Jupiter. He was a prominent figure in Babylonian cosmology, especially in the Enūma Eliš creation myth.

The Statue of Marduk, also known as the Statue of Bêl (Bêl, meaning "lord", being a common designation for Marduk), was the physical representation of the god Marduk, the patron deity of the ancient city of Babylon, traditionally housed in the city's main temple, the Esagila. There were seven statues of Marduk in Babylon, but 'the' Statue of Marduk generally refers to the god's main statue, placed prominently in the Esagila and used in the city's rituals. This statue was nicknamed the Asullḫi and was made of a type of wood called mēsu and covered with gold and silver.

Similar to statues of deities in other cities in Mesopotamia, the Babylonians conflated this statue with their actual god, believing that Marduk himself resided in their city through the statue. As such, the statue held enormous religious significance. It was used during the Babylonian New Year's festival and the kings of Babylon incorporated it into their coronation rituals, receiving the crown "from the hands" of Marduk.

Tishpak (Tišpak) was a Mesopotamian god associated with the ancient city Eshnunna and its sphere of influence, located in the Diyala area of Iraq. He was primarily a war deity, but he was also associated with snakes, including the mythical mushussu and bashmu, and with kingship.

Tishpak was of neither Sumerian nor Akkadian origin and displaced Eshnunna's original tutelary god, Ninazu. Their iconography and character were similar, though they were not formally regarded as identical in most Mesopotamian sources.
