An ancient civilisation of Nomad people who established themselves in the desert before handing their empire over to the Romans may have refused to write in a bid to save their hidden secrets, some researchers believe.
The Nabataeans emerged as a homogenous civilisation in the 4th century BC and their influence stretched from modern-day Yemen to Damascus, Syria, and from western Iraq into the Sinai Desert.
Despite extensive research, over the years historians have not been able to determine the exact borders of the civilisation's political control or the extent of their travels because they did not leave written testimonies as others, such as ancient Egyptians, did.
