What is "gaetuli"

Gaetuli was the romanised name of an ancient Berber tribe inhabiting Getulia. The latter district covered the large desert region south of the Atlas Mountains, bordering the Sahara. Other documents place Gaetulia in pre- Roman times along the Mediterranean coasts of what is now Algeria and Tunisia, and north of the Atlas. The Zenatas are believed to be descendants of the Gaetuli.
