Coloured illustrated front cover of the science/romantic fiction novel by Jules Verne.

The Green Ray Translated from the French by M de Hauteville Author: Verne, Jules / London: Sampson Low & Co, 1883. Language: English Source/Shelfmark: 12510.o.1 front cover Green flashes and green rays are rare optical phenomena that occur shortly after sunset or before sunrise, when a green spot is visible for a short period of time above the sun, or a green ray shoots up from the sunset point. It is usually observed from a low altitude where there is an unobstructed view of the horizon, such as on the ocean. The idea in the novel that one can predict where and when to observe the green ray has no scientific basis.
