Nabu (cuneiform: 𒀭𒀝 Nabû ܢܵܒܼܘܼ\ܢܒܼܘܿ\ܢܵܒܼܘܿ Nāvū or Nvō or Nāvō) is the ancient Mesopotamian patron god of literacy, the rational arts, scribes, and wisdom. The Akkadian "nabû" means 'announcer/authorised person', derived from the Semitic root N-B. It is cognate with the Syriac ܢܒܝܐ (nvīyā), Arabic نبي (nabiyy), and the Hebrew נביא (naví), all meaning 'prophet'. Nabu was worshiped by the Babylonians and the Assyrians. Nabu gained prominence among the Babylonians in the 1st millennium BC when he was identified as the son of the god Marduk. Nabu was worshipped in Babylon's sister city Borsippa, from where his statue was taken to Babylon each New Year so that he could pay his respects to his father. Nabu's symbols included a stylus resting on a tablet as well as a simple wedge shape; King Nabonidus, whose name references Nabu, had a royal sceptre topped with Nabu's wedge. Clay tablets with especial calligraphic skill were used as offerings at Nabu's temple. His wife was the Akkadian goddess Tashmet. Nabu was the patron god of scribes, literacy, and wisdom. He was also the inventor of writing, a divine scribe, the patron god of the rational arts, and a god of vegetation. As the god of writing, Nabu inscribed the fates assigned to men and he was equated with the scribe god Ninurta. As an oracle he was associated with the Mesopotamian moon god Sin. In the Babylonian tradition, planet Mercury was connected with Ninurta (as well as Saturn); because in the MUL.APIN Ninurta is consistently identified with Mercury, and it is read that: "Mercury whose name is Ninurta travels the (same) path the Moon travels." As Marduk took over the role of King of the gods from Enlil and inherited both his cultic roles and epithets as well as his position within the pantheon – the role of the most important son of the father of the gods that had previously belonged to Ninurta as son of Enlil (now replaced by Marduk); was thus taken over by Nabu, and Nabu became associated with the planet Mercury as well as being given connections with the moon god Sin, because as addressed in the MUL.
