Roman Empire [SEP] Local languages and linguistic legacy
References to interpreters indicate the continuing use of local languages other than Greek and Latin, particularly in Egypt, where Coptic predominated, and in military settings along the Rhine and Danube. Roman jurists also show a concern for local languages such as Punic, Gaulish, and Aramaic in assuring the correct understanding and application of laws and oaths. In the province of Africa, Libyco-Berber and Punic were used in inscriptions and for legends on coins during the time of Tiberius (1st century AD). Libyco-Berber and Punic inscriptions appear on public buildings into the 2nd century, some bilingual with Latin. In Syria, Palmyrene soldiers even used their dialect of Aramaic for inscriptions, in a striking exception to the rule that Latin was the language of the military.
