M. Jules Oppert (b.1825) was a famous linguist and translator , dealing with Mesopotamian cultures. He is known for his work deciphering Sumerian Cuneiform clay tablets, some of the earliest known writing. These messages were achieved with a stylus in damp clay, then hardened.
In case your Cuneiform has gotten rusty, the sample shown says, roughly, “Rhinos are mighty fine critters”.
Thank you for your good work, M. Oppert.
