(I found this part very interesting)
Previous finds from the remains of the royal palace include intact burial chambers and 73 tablets inscribed in a hybrid of Akkadian and Hurrian, likely the original language of what is today Turkey and the Caucasus.
The royal correspondence includes a 3,000-year-old warning from Hittite general Hanutti to the king of Qatna Idanda, telling him to prepare for war.
