Right now I'm writing an essay on Death in Venice, and I'm having trouble finding the right word or phrase to express how Aschenbach is parallel to the old man on the boat to Venice (both dress up to fit in with youth, some repetition of specific phrases in descriptions, youth from Pola vs youth from Poland, etc.).
The closest word I can find to describe what is a "parallel". I see this word used a lot on the internet to describe (usually in TV shows) when something that one character did in a past episode is similar to something that a character (usually different, but I've also seen it used to point out character development via slight differences in the parallel).
It kind of describes two completely separate scenes that have a much more powerful meaning when juxtaposed (usually very blatant mirroring, etc. to point this out to viewer/reader). In my case, it would be the scene with Aschenbach observing the man on the boat and the scene where Aschenbach applies makeup for Tadzio.
Specifically, the man on the boat foreshadows the "endgame" for Aschenbach. In my essay, I've referred to it mostly as foreshadowing, but I think the depth of the connection that Mann makes warrants something a little stronger. The word foil came to mind, in terms of the intensity and how it's character specific, but obviously, it has the opposite meaning of what I'm going for.
I did think about just using the word "parallel", but I when I looked it up, the definition for the word parallelism came up, and as a literary term it seemed from this definition, it seems that this word as a literary device refers to parallel syntax and a not to a broader similarity.
I've come up with "symmetry" and "mirror" to describe individual aspects, but I was wondering if there is a proper term that encompasses the broad connection between the two characters.
