British Library has digitised most of the known inscriptions and these are described in Biagetti et al.69 Although the inscriptions are in Berber characters, only some are decipherable. Various reasons for this have been suggested; either the messages were deliberately coded, so that only specific readers could understand them. Alternatively, they may have had a ‘ludic’ nature. The most exciting possibility is that they were in a non-Berber language, perhaps Nilo-Saharan or something unknown.
