Nabu, major god in the Assyro-Babylonian pantheon. He was patron of the art of writing and a god of vegetation. Nabu’s symbols were the clay tablet and the stylus, the instruments held to be proper to him who inscribed the fates assigned to men by the gods. In the Old Testament, the worship of Nebo is denounced by Isaiah (46:1).
Samsuditana, the last king of the 1st dynasty of Babylon (reigned 1625–1595 bc), introduced a statue of Nabu into Esagila, the temple of Marduk, who was the city god of Babylon. Not until the 1st millennium bc, however, did the relationship between Marduk and Nabu and their relative positions in theology and popular devotion become clear. Marduk, the father of Nabu, took precedence over him, at least theoretically, in Babylonia. But in popular devotion it was Nabu, the son, who knows all and sees all, who was chief, especially during the centuries immediately preceding the fall of Babylon. He had a chapel named Ezida in his father’s temple Esagila, where at the New Year feast he was installed alongside Marduk. In his own holy city, Borsippa, he was supreme. At this time Nabu was also a prominent deity in Assyria, where several temples were devoted to his worship.
Goddesses associated with Nabu were Nana, a Sumerian deity; the Assyrian Nissaba; and the Akkadian Tashmetum, queen of Borsippa, stepdaughter of Marduk, and, as her abstract Akkadian name indicates, Lady of Hearing and of Favour. She was rarely invoked apart from her husband, Nabu, whose name means “speaking.” Thus, while Nabu speaks, Tashmetum listens.
