We determine the epimorphisms A --> W from the Artin group A of type Gamma onto the Coxeter group W of type Gamma, in case Gamma is an irreducible Coxeter graph of spherical type, and we prove that the kernel of the standard epimorphism is a characteristic subgroup of A. This generalizes an over 50 years old result of Artin
