Proust suggests that his character Swann looks something like this:

Luini’s fresco “The Adoration of the Magi”

And Swann’s lover and tormentor, Odette, he sees this way:

Botticelli’s Zipporah, Jethro’s daughter from “The Trials of Moses”

I like Proust’s use of image references and also music references…. cool.
