This morning I captured this image of this spectacular Etruscan vase, as the writer Jules Verne called it, with the fishermen fishing for Las Fotos de los Lectores de La Vanguardia, on Gavà beach.

This is the so-called Omega effect. It is formed when the air, in contact with the surface, very dense and at the same time warmer, produces the refraction of light, which deforms the sun and creates the mirror effect.

When we observe this optical illusion it seems 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 arouse 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.
