Most people didn't go more than a few miles from where they were born their whole lives
Have you read of the work being done near Stonehenge? Through DNA analysis it is now widely believed that it was a centre of national pilgrimage, with folk travelling from as far away as Scotland along well-established roads to celebrate at key phases of the year.
Or we can move ahead and look at the building of the great monasteries. Are you saying that this skilled construction was done by toothless, starving villeins? Not travelling, well-compensated craftsmen?
We are seeing near the pyramids settlements for workers. It seems they were not actually Israelite slaves, but well-provisioned artisans and engineers.
The point of saltwater fishery products is actually important. Roman garum containers are found all across Europe, a testament to the importance of fish in the Roman diet, and to the widespread trade. Were these traders toothless serfs?
If we look then to the Anglo Saxon and then into the Norman we find Lex mercatoria, indicating a great and structured trade, again all across Europe. Bustling ports. Commerce. Legal structure available to traders.
And along the Mediterranean, the great Venetian trade between Asia and Europe. Wool, spices, dyes. Food.
Let there be no doubt that life during feudalism was no picnic. Very few people had air conditioning or hoovers or ready meals. And of course most were illiterate.
But there is much more to our human history than this snapshot of a serf in a mud hut in the midlands. Skilled carpenters and engineers. Blacksmiths and barrel-makers and shipbuilders and glassblowers. Often moving about....creating an entire class of journeymen. Traders. Soldiers of fortune. Bandits and thieves. Monks and scribes and entertainers. Squires and Junkers.
