. If S O is a Riemann surface with a complete metric of finite area and constant curvature -1, let S C denote the conformal compactification of S O. We show that, under the assumption that the cusps of S O are large, there is a close relationship between the hyperbolic metrics on S O and S C. We use this relationship to show that , where the Platonic surface P k is the conformal compactification of the modular surface S k.
