Mauretania, was a Spaniard, and the army he led into Africa was made up,
for the most part, of Gauls. Later on, under Arcadius, another Gaul,
Rufinus, shall be master of the whole of the East.

An active mind like Augustin's could not remain indifferent before this
spectacle of the world thrown open by Rome to all men of talent. He had the
soul of a poet, quick to enthusiasm; the sight of the Eagles planted on
the Acropolis at Carthage moved him in a way he never forgot. He acquired
the habit of seeing big, and began to cast off race prejudices and all the
petty narrowness of a local spirit. When he became a Christian he did not
close himself up, like the Donatists, within the African Church. His dream
was that Christ's Empire upon earth should equal the Empire of the Caesars.

Still, it is desirable not to fall into error upon this Roman unity.
Behind the imposing front it shewed from one end to the other of the
Mediterranean, the variety of peoples, with their manners, traditions,
special religions, was always there, and in Africa more than elsewhere.
The population of Carthage was astonishingly mixed. The hybrid character
of this country without unity was illustrated by the streaks found in the
Carthaginian crowds. All the specimens of African races elbowed one another
in the streets, from the nigger, brought from his native Soudan by the
slave-merchant, to the Romanized Numidian. The inflow, continually renewed,
of traffickers and cosmopolitan adventurers increased this confusion.
And so Carthage was a Babel of races, of costumes, of beliefs and ideas.
Augustin, who was at heart a mystic, but also a dialectician extremely fond
of showy discussions, found in Carthage a lively summary of the religions
and philosophies of his day. During these years of study and reflection he
captured booty of knowledge and observation which he would know how to make
use of in the future.
