What if street writing is not a prank, but a clear code? Pishasao is the sharp, angular graphics of São Paulo, born from political slogans and becoming a language of protest. Pishasao is not "scribbles", but a precise system of signs that emerged in São Paulo at the intersection of politics and street romance. Its angular letters stretch upward along facades like ladders and are read not in the familiar horizontal manner, but according to the principle of body movement: when writers climb onto ledges, they leave a lightning-signature on the concrete. Lecture attendees will learn how slogans from the 1960s-80s grew into a unique font and an entire ethics: why each letter must "hold the facade", how places are chosen, what distinguishes name writing from classic graffiti and street art, and where the line is drawn between art and vandalism. The lecturer will show the "black rivers" of letters on the highways of São Paulo, inscriptions on rooftops and bridges, actions that appeared at the Berlin Biennale and in European galleries, and responses in the Russian graffiti community. The lecturer is Artemiy Ananyev, a graduate of the Institute of Anthropology and Ethnology of RGGU. He will share historical-ethnographic observations, field interviews, and examples, show visual material, and explain why Pishasao cannot be reduced to simply "ruining a wall". This is important for those interested in contemporary art and for those studying urban movements and subcultures. Entertainment in Moscow is collected on our website.
