Writing the desert: the ‘Tifinagh’ rock inscriptions of the Tadrart Acacus (southwestern Libya)

The mountain ranges of the Tadrart Acacus and Messak in southwestern Libya (central Sahara) are widely known for their outstanding rock art inventory and some key prehistoric sites. This paper illustrates the preliminary outcomes of current investigations on the ‘Tifinagh’ inscriptions of the Tadrart Acacus the recording of which has recently increased thanks to the support of ‘Endangered Archives Programme’ of the British Library. Its aim is twofold: first, to outline the main steps of the project, placing these within the most relevant issues related to the phenomenon of writing in the Sahara, and second, to describe the results that have been achieved to date and to foresee possible avenues of development. In fact, although difficulties in both dating and decipherment have been repeatedly stressed through the years, we emphasise that Tifinagh texts can play an important role in the process of landscape interpretation. A proper ‘written landscape’, where humans left readable signs of their passages or their stays, can integrate other archaeological approaches pursued so far in the Tadrart Acacus and its surroundings.
