Transcendence, Excalibur and how Britons forgot how to make steel
I like to have at least a couple of books on the go at all times and two of my current crop – ‘Transcendence’ by Gaia Vince and Bernard Cornwell’s ‘Enemy of God’ – have provoked an unlikely fusion of ideas: was King Arthur’s unbreakable sword, Excalibur, a mythic expression of the lost art of Roman steel-making? Did Merlin wield ‘magic’ by exploiting the human brain’s ability to convert mental anticipation into physical reality?
