Is there a term for misperceiving a historical relationship between two works, images or tropes so that the earlier of the two is falsely thought to have derived from the later one?
I was thinking about this in terms of the inevitability of some movie critics thinking that the film version of The Dark is Rising is a rip-off of Harry Potter when in fact its source fiction predates Potter by a considerable margin.
I remember a similar instance when I was working on my Saturday morning cartoons book: I came across a TV critic who denounced one version of Super Friends because he thought the character of Darkseid was an outrageous ripoff of Darth Vader, when in fact Darkseid predates Darth Vader by seven years.
I also recall thinking when I was a kid, the first time I saw the TV show The Honeymooners, that it was a rip-off of the Warner Brothers mice cartoons.
Is there actually a term for this? If not, let’s invent one.
