Abstract: Let M be a compact Riemannian globally symmetric space of rank one. A theorem due to Helgason states that the antipodal manifold $ {A_x}$ of a point $ x \in M$ is again a symmetric space of rank one. We compute the multiplicities of the restricted roots of $ {A_x}$ from those of M, obtaining a very convenient way to determine $ {A_x}$.
