Nydam-Kragehul spatha from Nydam.

[Medicus matt]

Beautiful work on the scabbard.
But György's right, you're not holding it as it should be held.
"Romans" (whatever that means), may have been shorter but that sword is 5th century Danish and Scando-Germanic people at that time were, on average, only an inch or so shorter in overall height so there'd be barely any noticeable difference in hand size.

Now, I don't care, because it's a nice enough sword and a lovely scabbard but archaeological evidence is archaeological evidence.
