The prominence given to Nebo, the god of Borsippa, during the reign of Adad-nirari IV is highly significant. He appears in his later character as a god of culture and wisdom, the patron of scribes and artists, and the wise counsellor of the deities. He symbolized the intellectual life of the southern kingdom, which was more closely associated with religious ethics than that of war-loving Assyria.

A great temple was erected to Nebo at Kalkhi, and four statues of him were placed within it, two of which are now in the British Museum. On one of these was cut the inscription, from which we have quoted, lauding the exalted and wise deity and invoking him to protect Adad-nirari and the lady of the palace, Sammu-rammat, and closing with the exhortation, "Whoso cometh in after time, let him trust in Nebo and trust in no other god".

The priests of Ashur in the city of Asshur must have been as deeply stirred by this religious revolt at Kalkhi as were the priests of Amon when Akhenaton turned his back on Thebes and the national god to worship Aton in his new capital at Tell-el-Amarna.

It would appear that this sudden stream of Babylonian culture had begun to flow into Assyria as early as the reign of Shalmaneser III, and it may be that it was on account of that monarch's pro-Babylonian tendencies that his nobles and priests revolted against him. Shalmaneser established at Kalkhi a royal library which was stocked with the literature of the southern kingdom. During the reign of Adad-nirari IV this collection was greatly increased, and subsequent additions were made to it by his successors, and especially Ashur-nirari IV, the last monarch of the Middle Empire. The inscriptions of Shamshi-Adad, son of Shalmaneser III, have literary qualities which distinguish them from those of his predecessors, and may be accounted for by the influence exercised by Babylonian scholars who migrated northward.

To the reign of Adad-nirari belongs also that important compilation the "Synchronistic History of Assyria and Babylonia", which deals with the relations of the two kingdoms and refers to contemporary events and rulers.

The legends of Semiramis indicate that Sammu-rammat was associated like Queen Tiy with the revival of mother worship. As we have said, she went down to tradition as the daughter of the fish goddess, Derceto. Pliny identified that deity with Atargatis of Hierapolis.[[466]]

In Babylonia the fish goddess was Nina, a developed form of Damkina, spouse of Ea of Eridu. In the inscription on the Nebo statue, that god is referred to as the "son of Nudimmud" (Ea). Nina was the goddess who gave her name to Nineveh, and it is possible that Nebo may have been regarded as her son during the Semiramis period.

The story of Semiramis's birth is evidently of great antiquity. It seems to survive throughout Europe in the nursery tale of the "Babes in the Wood". A striking Indian parallel is afforded by the legend of Shakuntala, which may be first referred to for the purpose of comparative study. Shakuntala was the daughter of the rishi, Viswamitra, and Menaka, the Apsara (celestial fairy). Menaka gave birth to her child beside the sacred river Malini. "And she cast the new-born infant on the bank of that river and went away. And beholding the newborn infant lying in that forest destitute of human beings but abounding with lions and tigers, a number of vultures sat around to protect it from harm." A sage discovered the child and adopted her. "Because", he said, "she was surrounded by Shakuntas (birds), therefore hath she been named by me Shakuntala (bird protected)."[[467]]

Semiramis was similarly deserted at birth by her Celestial mother. She was protected by doves, and her Assyrian name, Sammu-rammat, is believed to be derived from "Summat"--"dove", and to signify "the dove goddess loveth her". Simmas, the chief of royal shepherds, found the child and adopted her. She was of great beauty like Shakuntala, the maiden of "perfect symmetry", "sweet smiles", and "faultless features", with whom King Dushyanta fell in love and married in Gandharva fashion.[[468]]

Semiramis became the wife of Onnes, governor of Nineveh, and one of the generals of its alleged founder, King Ninus. She accompanied her husband to Bactria on a military campaign, and is said to have instructed the king how that city should be taken. Ninus fell in love with Semiramis, and Onnes, who refused to give her up, went and hanged himself. The fair courtesan then became the wife of the king.
