Dutch? We are talking about Late antiquity. Again, my point is that Roman empire was a totally different world. In all senses.
About the Netherlands. Do not understand your question. I do not know a lot about Dutch trade empire, but my knowledge is sufficient to conclude that they were a technological leader. Their emipre stretched from Moluccas to South Africa, they basically invented capitalism as it is and created first full-time stock exchange.
Please elaborate what do you want to ask here.
Thanks.
Basically says the same.
