What is "antalas"

Antalas (; c. 500 – after 548) was a Berber tribal leader who played a major role in the wars of the Byzantine Empire against the Berber tribes in Africa. Antalas and his tribe, the Frexenses of Byzacena, initially served the Byzantines as allies, but after 544 switched sides. With the final Byzantine victory in 548, Antalas and his Christian tribe once again became Byzantine subjects. The main sources on his life are the epic poem Iohannis of Flavius Cresconius Corippus and the Histories of the Wars of Procopius of Caesarea.
