JKR describes the goblins in the book as: (this is taken from HP wiki) Physical appearance
Goblins were short and fair-skinned, as they spent very little time outside. They had very long fingers and feet, dome-shaped heads and were slightly larger than house-elves. Griphook, one of the hundreds of goblins working at Gringotts, had a bald head, pointed nose, and pointed ears. Some had dark, slanted eyes, and some goblins even wore pointed hats.[4]
why are they referring to 'hooked noses'? I think anti-semitism is rife, personally, but cant see it here.
