A veritable historical badass. For the uninitiated, Gotz was a mercenary who had fought for Frederick of Brandenburg, the Emperor Maximilian I, Albert IV of Bavaria, and a bunch of other Early Modern notables. Famously, Gotz lost his right arm during a siege when, in an incredibly unlikely turn of events, an enemy cannon ball hit the edge of his sword, forcing it down onto his hand and cutting it off.
So, there I think we see an element of Jaime’s mutilation. Unlike the Lannisters, however, Berlichingen was a practical man, if somewhat hot-tempered (Gotz was known for a number of feuds and duels, occasionally capturing various counts or raiding Nuremberg merchants), and he built himself a prosthetic that wasn’t made of a single piece of gold and thus completely useless. Gotz’ prosthetic used a system of hinges and straps to allow the hand to grasp objects. And so Gotz kept on keeping on.
Gotz was also a significant player in the German Peasants’ War of 1524-5, and although he ended up fighting on both sides, was one of the few professional soldiers who fought for the rebels. As a result, Goethe wrote a play about his life, in which Gotz is portrayed as a heroic individualist and national hero. Famously, during the third act, Gotz is put under siege by the imperial army, and when asked to surrender, says:
Mich ergeben! Auf Gnad und Ungnad! Mit wem redet Ihr! Bin ich ein Räuber! Sag deinem Hauptmann: Vor Ihro Kaiserliche Majestät hab ich, wie immer, schuldigen Respekt. Er aber, sag’s ihm, er kann mich im Arsche lecken!
(Me, surrender! At mercy! Whom do you speak with? Am I a robber! Tell your captain that for His Imperial Majesty, I have, as always, due respect. But he, tell him that, he can lick me in the arse!)
I'm writing for a character in a medieval fantasy setting, with full plate armor and knights, but guns aren't really a huge thing yet. However, he's lost his left hand just above the wrist (thankfully, he's right-handed). If he was able to get his hand(s?) on a metal prosthetic like the one used by Gotz von Berlichingen, what sorts of options would he have if he wanted to keep fighting? Could he strap a shield to the prosthetic and fight effectively?
Well, looking at Götz von Berlichingen would suggest, “yes.“
Götz lost his right hand in combat, and continued fighting in various campaigns for nearly 40 years via the use of a prosthetic.
So, I’m inclined to say, yes.
It’s worth pointing out, both of his prosthetic hands, were custom designed pieces.
If you’re wanting to work with a character like this, reading up on
probably isn’t a bad starting point.
