Battle of Courtrai by Angus McBride
The guy in the middle is holding a goedendag.
Correct, I wonder why it´s depicted so short though. You can´t stop charging cavalry with something that short I think. Also:
The goedendag was probably set in the ground secured by the fighter's foot and aimed with both hands
From the article you linked.
Its body was a wooden staff roughly 90 cm to 150 cm (3 to 5 feet) long
Checks out. It's a combination of a club and spear. I'd imagine the shorter version is more on the club side, while the longer one is more on the stabby side.
This is actually a screenshot of me making my way up the hill to Stormveil Castle in Elden ring lol
A favorite! DES GILDEN VRIEND!
