We report the discovery of two galaxies with (I-K)~6.5 lying near the line of sight to the z = 3.790 quasar PC 1643+4631 A. Based on the spectral energy distributions and angular extents of the objects we suggest that the most likely interpretation is that they are elliptical galaxies lying at z~2.4 The existence of such evolved objects at this redshift would imply a current age of the universe substantially in excess of 1.0 X 10^10^ yr for q_0_ = 0.02, and 1.9 X 10^10^ yr for q_0_ = 0.5. It would also imply that at least some large luminous galaxies were already fully formed at z > 6.
