It is proved here that if f : C → C ¯is an elliptic function and q is the maximal multiplicity of all poles of f , then the Hausdorff dimension of the Julia set of f is greater than 2 q /( q + 1), and the Hausdorff dimension of the set of points that escape to infinity is less than or equal to 2 q /( q + 1). In particular, the area of this latter set is equal to 0. 2000 Mathematics Subject Classification 37F35 (primary); 37F10, 30D30 (secondary).
