Not read the article and don't know who made it, but you have to remember that a lot of academics don't necessarily have "work knowledge". Folks like Toddy actually do stuff in real life too. Mate of mine surprised some of the academics as to how he attached a bronze socket head to the handle. They'd not seen it before, but it just made sense to him. Also they used a load of carnival folk in Italy and Greece to see how they moved large awkward things with minimal kit.
To be fair, the guy had sought advice from basket makers.
