Today at dawn on Gavà beach, in Baix Llobregat, we were able to admire this spectacular Etruscan vase, as the novelist Jules Verne defined the Omega effect. I have captured an image for La Vanguardia's Readers' Photos.
The so-called Omega effect is formed when the air, in contact with the surface, which is very dense and at the same time warmer, produces the refraction of light, which deforms the sun and creates the mirror effect.
When observing this optical illusion it appears that the base of the sun rests its "foot" on the horizon line that separates the sea from the sky.
Optical effects caused by Earth's atmosphere can cause distant objects near the horizon, including the Sun and Moon, to take on shapes that not only pique our attention or surprise us, but invite us to imagine.
This is how the writer Jules Verne had the impulse to compare this Omega effect with the shape of an Etruscan vase, looking for a reference to define its shape.
