As the sun eclipses the stars by its brilliancy, so the man of knowledge will eclipse the fame of others in assemblies of the people if he proposes algebraic problems, and still more if he solves them.

Quoted in F Cajori,

A person who can, within a year, solve *x*^{2} - 92*y*^{2} = 1 is a mathematician.
