In this chapter, names attested in the new edited ostraca from Gigthi and Assenamat are analysed from the point of view of Palaeo-Amazigh linguistics and in relation to the names of Bu Njem and of Roman Africa as a whole. Special attention is devoted to personal names of carriers involved in commercial exchanges as well as some measures that are unusual in Latin. These new contributions of onomastic material yield some personal names already documented in other regions of North Africa and add new names that can be analysed as Palaeo-Amazigh on phonological, morphological, lexematic, and semantic grounds. The linguistic analyses are put into the geohistorical, cultural, economic, and epigraphic contexts in which Tripolitanian ostraca were written. The study of measures portrays a depiction of Palaeo-Amazigh groups (Garamantes amongst them) as suppliers of grain and other crops cultivated in Phazania (Fazzān) and in northern Sahara to the Roman frontiers thanks, on the one hand, to sophisticated systems of water extraction whose true extent has only recently been revealed by archaeological prospection focused on hydraulic engineering and, on the other hand, to skin or leather bags used as containers for grain, water, and other supplies in Trans-Saharan transportation.
