Newbie pronunciation question

[Nathan Ross]

HOWEVER we know that from an early period people specifically attempted to change their elocution...so I'd be sort of surprised if he didn't manage to de-punicise.

I believe it's the dubious Historia Augusta that mentions Severus retaining a Punic accent until old age - but Birley, I think, found it 'plausible'.

the V in Latin was indeed a /w/ for a long period of time, but obviously before we get to Juvenal's time this was changing.

That's good to know! So we don't have to call the Wigiles or read Wegetius! Why specifically before Juvenal though?
