We present a family of stable rectangular mixed finite elements for plane elasticity. Each
member of the family consists of a space of piecewise polynomials discretizing the space
of symmetric tensor fields in which the stress field is sought, and another to discretize
the space of vector fields in which the displacement is sought. These may be viewed as
analogues in the case of rectangular meshes of mixed finite elements recently proposed
