Imagine being the kings son and being raised not for the throne but for an administrative or priestly office, and you learn how to read and write.
Then you somehow become the king after all and are very proudfull that you CAN read and write, (Assyrian kings can’t generally) and decide to build a massive library.
You also invaded Chaldea, destroyed Elam, conquered Egypt, sacked Thebes.
Ninevah is your capital and you order to make a giant reliëf depicting you hunting lions.
Decades later your empire gets destoyed and 2500 years later archeologists dig up your massive library.
And nobody talks about you because people only want to talk about the Roman Empire and WW2.
