 Ring-shaped gravitational mirages are referred to as Einstein rings, and one multiple-image gravitational mirage is named the Einstein Cross, as tribute for Einstein's predictions regarding gravitational lensing.Gravitational bending of light was predicted by Einstein's general relativity in 1916, and first observed by astronomers in 1919 during a total solar eclipse.Accurate measurements of stars seen in the dark sky near the eclipsed Sun indicated a displacement in the direction opposite to the Sun, about as much as predicted by Einstein's theory.
