Hi Lex, I just composed a long reply to this and the computer crashed. I am so angry

Right, to repeat...

Your point is valid on one level

! But the thing is with barbarous coins they are so often garbled. There are so many types which are not technically correct (e.g. Salus with cornucopia etc) that I do not think we should be too concerned with the prototype of any particular barbarous issue. Look at this one - a
Constantinopolis
bust with an VRBS ROMA legend. Similar garbled coins are always turning up in the barbarous series.
Style
is different. Style represents the way a particular engraver treats particular features of a design. What differentiates my, for example, Mint II style 1a coins from my 2b, is the different treatment of a number of variables. These variables define my stylistic considerations. They enable (1) the viewer to define whether a coin is an imitation or not and (2) to (if the coin falls into a known group) define which group that barbarous coin belongs to.
We may well be approaching this question from different angles and I am not saying that searching for a prototype is irrelevant but I am saying that it is not always the best way of dealing with these coins. Barbarous coins are often (as you stated yourself in an earlier thread)
interpretations
of a particualr type. I don't always think it is particularly worthwhile to search for the particular original (if there was just one original) type for an imitation; I prefer to concentrate on the stylistic attributes of the imitation itself.
Only by doing this, I would argue, can we truly begin to categorise these imitations. The original is not important - it is the attributes of the imitation we must study.
Sorry for the lack of smilies - I'm not really being grumpy - I just want to kill my computer

Best regards,
Adrianus
BY THE WAY - ARE ANY READERS OF THIS FORUM GOING TO THE LONDON COIN FAIR THIS SATURDAY???
