Hey guys! Very sorry for posting so late, my internet has been down. Despite that, I must say I had a great time touring the exhibit and learned a great deal of new info from Amber. My favorite parts were the tombstones and slabs with ancient Arabic written on them. It surprised me how similar the script looked to Greek and that the two countries even had interaction with each other. While we were advised to take everything with a grain of salt and some descriptions were obviously propaganda, I still couldn't help but be amazed at what the government's archaeologists managed to excavate. I feel so lucky to have been able to see the exhibit before the general public and plan to see all of it in the next coming months.
Here's an example of a tombstone that would be found in al-Ma'la (north of Mecca) and the ancient southern Arabian Arabic alphabet. Unfortunately, I couldn't find any pics of the slabs on display but this should give you an idea of what the written language looked like.
