“Have you ever witnessed the sun setting over the sea? (…) But did you notice a phenomenon that occurs at the moment when the radiant star casts its last ray when the sky is completely clear and transparent? Perhaps not. Well, don’t miss the opportunity to witness this phenomenon. Your eyes will perceive, not a red ray, but a marvellous green ray, of a colour, which no painter can reproduce on his palette, and which Nature herself has not repeated either in the various shades of plants, or in the most transparent colour of the seas. If there is green in paradise, it can only be this green, which is, without doubt, the true green of hope.” Jules Verne.
This is how Jules Verne described the article in an English newspaper that would captivate the protagonist of his novel “The Green Ray”, and for which he would undertake a series of trips in order to contemplate such a singular phenomenon. The Atlantic coast of Galicia is a fantastic place to see this optical lesson, which is nothing more than the refraction of the light generated by the last rays of sunlight as they pass through the atmosphere under specific climatic circumstances.
“…we have not seen this ray that we have been looking for so much. -We have seen something better,” Helena said quietly. We have seen the same happiness, which legend attributes to the observation of this phenomenon. And since we have found it, my dear Olivier, we need nothing more, and we can give to those who do not know it and want to know it, the famous green ray!” Jules Verne.
