The article by Leonardo Padura explores the historical figure of Juan José Castelli, an Uruguayan lawyer who played a crucial role in the May Revolution, which ultimately led to the independence of the provinces of the Viceroyalty of the Río de la Plata from Spain. Known as 'The Orator of Mayo,' Castelli was instrumental in establishing the first government council that would pave the way for emancipation. His untimely death in 1812, shortly after the uprising, prevented him from witnessing the subsequent developments of the republics he strived to free. His battle with tongue cancer, which was described in a poetic but grim manner, adds a tragic dimension to his life story.
