Meh. Whatever the shape of the letter, the important thing to know is that the Romans did not distinguish vocalic and consonantal V/u
. Take a look here
to see all sorts of examples of written Latin from antiquity to the Middle Ages. You'll soon realize just how similar they all are, and how they're really just different styles of the same letter. It's no different from us moderns having several variations of single letters in both print and handwriting, e.g. a/a
The litterae quadratae
or "square letters", upon which our modern capitals are based, were mostly used for inscriptions and always had the angular V. Other types of Latin writing had different forms of this same letter, some with a similar angular shape but a rounded base, others completely rounded like our U
, and still others with a tail like our u
. It's erroneous to say that the Romans had one but not the others.
