Greek Fire from the Chronicle of Ioannis Skylitzis, mid-12th mid-13th century, Biblioteca Nacional, Madrid
Could this be related, somehow, to so-called “Greek Fire”?
Given that the article said “The steam cannons could have fired hollow balls made of clay and filled with something similar to an incendiary chemical mixture known as Greek fire...” I’m going to go out on a limb and say “yes”.
Sorry, couldn’t resist.
