Two authors will talk about the Spanish-language universe. As a homage to the next Language Congress in Arequipa, the Mexican writer Gonzalo Celorio and the Arequipa writer Carlos Herrera will talk to Alonso Ruiz Rosas about the diversity of Spanish, the richness of a language spoken all over the world, but particularly linked to Latin America; cultural traditions, scientific discoveries and major literary landmarks in the language that unites us.
