The complete set of analytic solutions of the geodesic equation in Schwarzschild-(anti)de Sitter space-times is presented. The solutions are derived from the Jacobi inversion problem restricted to the set of zeros of the theta function, called the theta-divisor. In its final form the solutions can be expressed in terms of derivatives of Kleinian sigma functions. The different types of the resulting orbits are characterized in terms of the conserved energy and angular momentum as well as the cosmological constant. An elaboration of the necessary steps of the explicit computation of the solutions is given.
