After his liberation from Auschwitz ,Primo Levi said: “Freedom. The breach in the barbed wire gave us its tangible image”.
The blue background symbolizes this freedom by returning to the light blue as Minerva’s colour.
Again, Athena-Minerva gives her name to the owl (Athene noctua)which in Greek and Roman mythology was the attribute of the goddess of wisdom ,was the symbol of clairvoyance and the light after the solution of a problem. That’s why, in the nineteenth century, with Hegel, the owl became the symbol of philosophy.
Its plaintive call, which I sometimes hear in the morning, announcing the rising sun, sounds to me like a message of hope.
