Most make no sense at all. They're not medieval looking versions of the logos, they're just random stuff in the shapes (many just vaguely) and colors of the modern logos.
I seriously don't understand what the designer is going for. It kinda feels like AI because of how weirdly unrelated the stuff depicted is, like you can see the original logo if you squint or blur your vision but when you actually see what the things depicted are it's just dumb and confusing.
