Note 039
From Chapter 2 of the Decline & Fall

The Celtic was preserved in the mountains of Wales, Cornwall, and Armorica. We may observe that Apuleius reproaches an African youth, who lived among the populace, with the use of the Punic; whilst he had almost forgot Greek, and neither could nor would speak Latin (Apolog. p. 596). The greater part of St. Austin's congregations were strangers to the Punic.
