Surprised that none of all you classically educated has pointed out that the reason Latin V was taken in "Reformed Pronunciation" to be pronounced like our W is that it was just a conventional way of writing our U: so that "Claudius" on an inscription would appear as "Clavdivs"; so before a vowel it would be pronounced as W. Hence some people's theory that "Dee-wayz" would have been correct for "Dives". But that theory is of early 20C origin — A P Herbert had some sarcastic things to say about it in the 1930s; so is unlikely to have appealed to source singers of 18-19C.
