Stone cannonball?

[LeonymusBosch]

Hello everyone,

I was recently asked to identify a possible cannonball and I would like some more opinions on this.



The finder said "iron cannonball, 16th c. removed from ground and walls of an Ottoman fort"

First off all, the ball is made of stone, not iron. It's 72 cm in circumference and 24 cm diameter and weighs 16 kg. The size of it makes it impossible to be iron or lead as it would have to be much heavier if solid. If it were iron, the only possibility for that kind of weight/size ratio for an iron one, the ball would have to be hollow, made as a shell for 18/19th c. howitzers and mortars. This is definitely not it, it's not perfectly round, it looks like stone with parts left unfinished, not magnetic ofc and there were certainly no large siege or rather fort mortars at the find location.





My thinking is this could possibly not be a cannonball at all, or it could be for late 15th or 16th century cannons. If yes, likely Ottoman as they had cannons large enough which would fire projectiles of this size, and there were multiple battles and sieges nearby in mid to late 16th c. but I'm unsure if they actually brought them to that location.

What do you think?
