“Nothing is known of the early history of the Library of the Temple of Nebo at Nineveh, but there is little doubt that it was in existence in the reign of Sargon II.
Authorities differ in their estimate of the attributes that were assigned to Nebo (Nabu) in Pre-Babylonian times, and “cannot decide whether he was a water-god, or a fire-god, or a corn-god, but he was undoubtedly associated with Marduk, either as his son or as a fellow-god.
It is certain that as early as B.C. 2000 he was regarded as one of the “Great Gods” of Babylonia, and in the fourteenth century B.C. his cult was already established in Assyria. He had a temple at Nimrûd in the ninth century B.C., and King Adad-nirari (B.C. 811-783) set up six statues in it to the honour of the god; two of these statues are now in the British Museum.
The same Adad-nirari also repaired the Nebo temple at Nineveh. Under the last Assyrian Empire Nebo was believed to possess the wisdom of all the gods, and to be the “All-wise ” and “All-knowing.” He was the inventor of all the arts and sciences, and the source of inspiration in wise and learned men, and he was the divine scribe and past master of all the mysteries connected with literature and the art of writing (dup-sharrute).
Ashur-bani-pal addresses him as “Nebo, the mighty son, the director of the whole of heaven and of earth, holder of the tablet, bearer of the writing-reed of the tablet of destiny, lengthener of days, vivifier of the dead, stablisher of light for the men who are troubled.”
In the reign of Sargon II the Temple of Nebo at Kuyûnjik was repaired, and probably at that time a library was housed in it. Layard found some of the remains of Nebo’s Library in the South West Palace, but it must have been transferred thither, for the temple of Nebo lay farther north, near the south corner of Ashur-bani-pal’s palace.
Nebo’s temple at Nineveh bore the same name as his very ancient temple at Borsippa (the modem Birs-i-Nimrûd), viz., “E-ZIDA.”
