This happened to me, but then I went to investigate where the name “campus” came from, since campus has nothing to do with sea in Greek. All I found is that there was a sea monster in Greek mythology of that name …
(In Percy Jackson, there are sea horse which are proper horses only of the sea, I’m not sure where Rick Riden took the inspiration for them from)
Interesting.
I wonder what I did wrong in the first time I searched for this that I couldn’t find anything.
So if I understand this correctly it is Greek mythology -> actual sea creature -> brain part.
