Abstract
This paper is concerned with the discriminant of a classical modular equation of prime level. Weber determined all its factors but not their multiplicities. This paper fills in that gap by presenting an explicit formula for the discriminant and its factors with multiplicities. Also a relation between a classical modular equation of prime level $p$ and that of level $p^2$ is presented.
