So why did the hook nose "become a thing" in discriminatory appearance?

[Thumpalumpacus]

Well the manuscript in the picture is from 800s i think. But what i am saying the so called demon noses or whatever. In modern times its more common with jewish stereotypes, so i am more looking for history to see if there is something behind it

https://en.wikipedia.org/wiki/Jewish_nose
Jewish nose or Jew's nose[1] is a racial stereotype[2] that refers to a hooked nose with a convex nasal bridge and a downward turn of the tip of the nose[3] that was singled out as a hostile caricature of Jews in mid-13th century in Europe, and has since become a defining element of the Jewish stereotype.

Of course there's something behind it. Jews were for centuries disparaged and discriminated-against in Europe. As a result, in art, they would use the nose to explicate their prejudices.
