Certain symbols appear on temple walls at various locations in the ancient city of Dūr-Šarrukīn, where Khorsabad, Iraq, is today. At the time of their creation, the city was ruled by Sargon II, who ruled over the Assyrian kingdom from 721 to 705 BCE. The king was already middle-aged by the time he took the throne (by force) from his brother, Shalmaneser V.

He was remembered as a great king who founded the Sargonid Dynasty, which ruled the Neo-Assyrian Empire for another century before it fell. He was particularly fond of building monuments as well as being a patron of the arts.

The region, which encompasses modern Iraq, parts of Iran, Turkey, and Syria is often regarded as the “cradle of civilization” today. It is the place where empires were first born, along with cities and even written language. It was an incredibly important area for much of human history, and so interpreting the symbols may help us understand more about the ancient humans that lived there.

The symbols tend to appear in the same sequence consisting of a lion, eagle, bull, fig tree and a plough. They were first recorded and transmitted to public audiences by French excavators who visited the location at the end of the 19^th century.

Since their rediscovery, many researchers have attempted to interpret their meaning. Some believe they are like Egyptian hieroglyphs, some sort of expression of imperial power, or may even spell out the king’s name.

But now an Assyriologist from Trinity College Dublin has proposed a new explanation: the symbols may spell out Sargon’s name (šargīnu), while also representing specific constellations.

“The study of ancient languages and cultures is full of puzzles of all shapes and sizes, but it’s not often in the Ancient Near East that one faces mystery symbols on a temple wall,” Dr Martin Worthington explained in a statement.   

According to Worthington, the symbols can also be understood as a constellation. For instance, the lion represents “Leo”, and the eagle “Aquilla”. Many of our existing constellations were inherited from the Greeks who themselves inherited those from Mesopotamia, so we would recognize them today. However, we have dropped others, including the “jaw”, which Worthington believes was represented by the symbol of the fig tree. This, he argues, comes from the belief that the word for “tree” – iṣu – sounds similar to that for jaw – isu.

“The effect of the five symbols, was to place Sargon’s name in the heavens, for all eternity – a clever way to make the king’s name immortal”, Worthington added. “And, of course, the idea of bombastic individuals writing their name on buildings is not unique to ancient Assyria…”.

Yet Worthington is aware that his idea is not set in stone, as it were. “I can’t prove my theory, but the fact it works for both the five-symbol sequence and the three-symbol sequence, and that the symbols can also be understood as culturally appropriate constellations, strikes me as highly suggestive. The odd[s] against it all being happenstance are – forgive the pun – astronomical”.

The study is published in the Bulletin of the American Society of Overseas Research.
