I've been checking all the mark up in the Argonauts bit of Apollodorus and they sail past the "Celtic Nation" (1.9.24) and we don't have any coordinates for it. I realise it's probably not all that useful to stick a a single point in what the Greeks called "celtic" and call it done, but is there any area that would be best to specify in this case? It should be around the south of France or North-West Italy Because they also go by Liguria. Any thoughts? ~Simon
