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