For over 100 years, archaeologists have been flummoxed by a set of symbols discovered at an ancient temple in Iraq—until now, Miami Herald reported.

An expert on Mesopotamia says he has decoded the symbols, revealing a “clever” double entendre, according to an article published in the Bulletin of the American School of Oriental Research.

The sequence of symbols—a lion, eagle, bull, fig tree and plough—was found etched into Assyrian temple ruins in the ancient city of Dur-Sarrukin, located in present day Khorsabad, Iraq.

The temples were constructed during the reign of King Sargon II, which spanned from 721 to 704 B.C., making them over 2,700 years old.

The etchings, comparable to Egyptian hieroglyphs, have been subject to various interpretations over the past centuries.

A 19th century scholar presumed they were nothing more than meaningless, aesthetically pleasing designs, while more recent scholars have taken them to be representations of gods.

But Martin Worthington, an Assyriologist at Trinity College Dublin, believes these interpretations do not tell the full story.

In the article, he contends that the symbols contain the sounds that “spell out” King Sargon II’s name.

Further supporting this claim is the fact that the shortened version of the sequence, also found at the temple, also spells out the king’s name.

But in addition to his name, the symbols can also be interpreted to represent specific constellations in the night sky, Worthington said.

Some are familiar to modern humans, including Leo, signified by the lion and Taurus, signified by the bull. The lesser known constellations of Aquila, Jaw, and Apin are also represented.

All five constellations “have associations which would have befitted an Assyrian king” since they are situated near stars associated with gods, Worthington said.
