Thanks guys.
I've heard from others that the crab was symbolic of joining Hannibal against
Rome but I haven't found anything to support that yet. The Brettian's were originally mountainous peoples who were not Greek so not sure when the crab became known to them. This is an
area where there is very little academic research available in English. Academia has some papers in
Italian but my academic
Italian isn't
very good. A great book I'm just finishing is "Between
Rome and
Carthage: Southern
Italy during the Second Punic War" by Michael Fronda. Some numismatic info but it's more about the rivalries between the various cities in Southern
Italy. A
very good read for anyone interested in the politics of Non-Roman
Italic peoples of the 2nd Punic war.
