The color purple and the roman laws...

[jpvdgiessen]

Purple dye was made by a mullosc or some other kind of shell fish that is believed to be extinct today.

Please give some references where this extinction is mentioned.

Even in Roman times it was very rare and expensive. Because of this, it's unlikely a barbarian would come by purple cloth unless he killed someone of very high rank in society.

Not if the cheaper purple color from the Madder is used, but Celts were living too far north, for making this purple from the Madder, because the plant was imported in the Netherlands and other areas in the 15th century. But if he was rich enough he could imported it, cities like Thyatira and Sardis were exporting this stuff.
