It disappears from some brands; in Germany it becomes a crime to expose it; in Padua someone used it to smear a wall in the local Pd section. It’s just a zeta, a stupid letter of the alphabet. In ours, the last one. But it happens to human signs that they become symbols: signs that, in themselves, can also be neutral, and almost always innocent. Let alone any letter of the alphabet, which without the alliance with other letters, whether they are vowels or consonants, can say very little. And Instead, apparently, he says. This zeta is not just a zeta. It is difficult to reconstruct the reasons that elected it as a symbol of the Russian invasion. But the fact that the path is opaque is less relevant than the ultimate, contagious, invasive effect. In some ways violent. What was the swastika before the Nazis? A sunny and auspicious symbol of the ancient Euro-Asian cultures. Then? It has become the most dismal and frightening and deadly sign of the last century. There are those who have made it the reason to humiliate and to kill. So, seeing that zeta standing out today on the facade of a building in the center of Moscow is something alarming. And precisely because the context is reassuring. But it’s not a publicity stunt, a trendy logo. It is, in some ways, already a weapon.
