Which book is this?
Okay first of all, having seen the amount of damage on real archaeological finds there’s no way an aluminum can survives for several centuries without disintegrating. In fact, it seems to be expected to take between 200 and 500 years.
But second, there’s no way that shape would be called a shield. Even if some archaeologist was silly enough to make that error there would be dozens of contemporary HBMA practitioners pouncing on the poor bastard with their arguments about practicality and various attempts at recreation and demonstration.
Unless this is assuming a sample with one half of the can worn away and the other preserved in some miraculously half-protective condition. Though I’d really expect the top and bottom to outlast the wall.
What the fuck
WTF indeed. I’m guessing someone messed up the original images and these went to the print or this is a book from alternate one of the dimensions.
Read the text. Is some kind of twisted joke, trying to fool us, making us believe that this is a real textbook.
I’m not falling in your tricks, OP. Try again tomorrow.
