His residence Cirta (Constantine)
became the stirring capital of a powerful state, and a chief seat of
Phoenician civilization, which was zealously fostered at the court of
the Berber king--fostered perhaps studiously with a view to the future
Carthagino-Numidian kingdom. The hitherto degraded Libyan nationality
thus rose in its own estimation, and the native manners and language
made their way even into the old Phoenician towns, such as Great
Leptis.
The Berber began, under the aegis of Rome, to feel himself
the equal or even the superior of the Phoenician; Carthaginian envoys
at Rome had to submit to be told that they were aliens in Africa,
and that the land belonged to the Libyans. The Phoenico-national
civilization of North Africa, which still retained life and vigour
even in the levelling times of the Empire, was far more the work
of Massinissa than of the Carthaginians.
