"When Shamshi-Adad V died in 810 BC, his son Adad-nirari III (810–782 BC) was too young for the kingship, and therefore his wife, Sammuramat, reigned a number of years for her son as regent. Her superior personality and the fact that she is the only woman ever to rule over Assyria made such a deep impression on her contemporaries and on later generations that under the name of Semiramis she became the central figure of numerous legends of antiquity that live on in Iraq to the present day." -- Nichol, Francis D., The Seventh-day Adventist Bible Commentary, (Washington, D.C.: Review and Herald Publishing Association) 1978.
This stela shows the king worshipping in front of the symbols of his gods. The large cross on his chest is a symbol of the sun god. I think the other symbols above his right hand are: the 8-pointed star representing Ishtar (Venus), the forked thunderbolt of Adad the storm god, the crescent disc of Sin the moon god, the frilly sun disc of Assur (or Ashur, after whom the Assyrians are named), and the beehive-shaped hat or tiara of Anu the sky god.
The king is dressed in a Babylonian robe and beard, indicating his role as king of Babylon after the defeat of Marduk-balassu-iqbi in 814 BC. The inscription (not shown) is dedicated to the god Ninurta, and gives an account of the king's campaigns up to 814 BC. It is written in a form of cuneiform used a thousand years earlier, apparently to give the impression of great age and authority.
