Imagery overlap between horses and gallows/death?
I'm doing some research for a story and I'm looking for imagery from Norse/medieval Germanic myth and folklore linking horses to gallows.
Obviously we have Sleipnir first and foremost, who is not just the horse of Odin the god of gallows but also appears on iconography next to figures with rope around their necks. I'm also aware of the three-legged Hel-horse which can kinda tentatively very maybe be linked to the 'three legged mare' model of three-legged gallows, and there's at least one horse/gallows kenning I'm aware of.
Aside from strictly the gallows-related stuff there's also folklore entities like the Bäcka-häst horse that would drown children, and the name Yggdrasil itself refers to either the 'terrible horse' or 'the terrible ones horse'.
Are you aware of any other similar cases rom that general corner of the world? I'd love to hear about them.
