Imaging with a spherical mirror in empty space is compared with the case when the mirror is filled with Maxwell's fish eye medium. Exact time-dependent solutions of Maxwell's equations show that perfect imaging is not achievable with an electrical ideal mirror on its own, but it is with Maxwell's fish eye in the regime where it implements a curved geometry for full electromagnetic waves.
